Log Message:
Update coreutils and gnuls to 8.13 (from the ancient 6.12).

In particular, I am doing this to fix the build under macppc.  6.12 is
just broken on machines that have a 64-bit time_t with a 32-bit long.

All of our local patches seem to have been assimilated upstream... but,
of course, this does not mean new problems won't arise!

This update has been tested on amd64, macppc and OS X 10.6.

* Noteworthy changes in release 8.13 (2011-09-08) [stable]

** Bug fixes

  chown and chgrp with the -v --from= options, now output the correct owner.
  I.E. for skipped files, the original ownership is output, not the new one.
  [bug introduced in sh-utils-2.0g]

  cp -r could mistakenly change the permissions of an existing destination
  directory.  [bug introduced in coreutils-6.8]

  cp -u -p would fail to preserve one hard link for each up-to-date copy
  of a src-hard-linked name in the destination tree.  I.e., if s/a and s/b
  are hard-linked and dst/s/a is up to date, "cp -up s dst" would copy s/b
  to dst/s/b rather than simply linking dst/s/b to dst/s/a.
  [This bug appears to have been present in "the beginning".]

  fts-using tools (rm, du, chmod, chgrp, chown, chcon) no longer use memory
  proportional to the number of entries in each directory they process.
  Before, rm -rf 4-million-entry-directory would consume about 1GiB of memory.
  Now, it uses less than 30MB, no matter how many entries there are.
  [this bug was inherent in the use of fts: thus, for rm the bug was
  introduced in coreutils-8.0.  The prior implementation of rm did not use
  as much memory.  du, chmod, chgrp and chown started using fts in 6.0.
  chcon was added in coreutils-6.9.91 with fts support.  ]

  pr -T no longer ignores a specified LAST_PAGE to stop at.
  [bug introduced in textutils-1.19q]

  printf '%d' '"' no longer accesses out-of-bounds memory in the diagnostic.
  [bug introduced in sh-utils-1.16]

  split --number l/... no longer creates extraneous files in certain cases.
  [bug introduced in coreutils-8.8]

  timeout now sends signals to commands that create their own process group.
  timeout is no longer confused when starting off with a child process.
  [bugs introduced in coreutils-7.0]

  unexpand -a now aligns correctly when there are spaces spanning a tabstop,
  followed by a tab.  In that case a space was dropped, causing misalignment.
  We also now ensure that a space never precedes a tab.
  [bug introduced in coreutils-5.3.0]

** Changes in behavior

  chmod, chown and chgrp now output the original attributes in messages,
  when -v or -c specified.

  cp -au (where --preserve=links is implicit) may now replace newer
  files in the destination, to mirror hard links from the source.

** New features

  date now accepts ISO 8601 date-time strings with "T" as the
  separator.  It has long parsed dates like "2004-02-29 16:21:42"
  with a space between the date and time strings.  Now it also parses
  "2004-02-29T16:21:42" and fractional-second and time-zone-annotated
  variants like "2004-02-29T16:21:42.333-07:00"

  md5sum accepts the new --strict option.  With --check, it makes the
  tool exit non-zero for any invalid input line, rather than just warning.
  This also affects sha1sum, sha224sum, sha384sum and sha512sum.

  split accepts a new --filter=CMD option.  With it, split filters output
  through CMD.  CMD may use the $FILE environment variable, which is set to
  the nominal output file name for each invocation of CMD.  For example, to
  split a file into 3 approximately equal parts, which are then compressed:
    split -n3 --filter='xz > $FILE.xz' big
  Note the use of single quotes, not double quotes.
  That creates files named xaa.xz, xab.xz and xac.xz.

  timeout accepts a new --foreground option, to support commands not started
  directly from a shell prompt, where the command is interactive or needs to
  receive signals initiated from the terminal.

** Improvements

  cp -p now copies trivial NSFv4 ACLs on Solaris 10.  Before, it would
  mistakenly apply a non-trivial ACL to the destination file.

  cp and ls now support HP-UX 11.11's ACLs, thanks to improved support
  in gnulib.

  df now supports disk partitions larger than 4 TiB on MacOS X 10.5
  or newer and on AIX 5.2 or newer.

  join --check-order now prints "join: FILE:LINE_NUMBER: bad_line" for an
  unsorted input, rather than e.g., "join: file 1 is not in sorted order".

  shuf outputs small subsets of large permutations much more efficiently.
  For example `shuf -i1-$((2**32-1)) -n2` no longer exhausts memory.

  stat -f now recognizes the GPFS, MQUEUE and PSTOREFS file system types.

  timeout now supports sub-second timeouts.

** Build-related

  Changes inherited from gnulib address a build failure on HP-UX 11.11
  when using /opt/ansic/bin/cc.

  Numerous portability and build improvements inherited via gnulib.

* Noteworthy changes in release 8.12 (2011-04-26) [stable]

** Bug fixes

  tail's --follow=name option no longer implies --retry on systems
  with inotify support.  [bug introduced in coreutils-7.5]

** Changes in behavior

  cp's extent-based (FIEMAP) copying code is more reliable in the face
  of varying and undocumented file system semantics:
  - it no longer treats unwritten extents specially
  - a FIEMAP-based extent copy always uses the FIEMAP_FLAG_SYNC flag.
      Before, it would incur the performance penalty of that sync only
      for 2.6.38 and older kernels.  We thought all problems would be
      resolved for 2.6.39.
  - it now attempts a FIEMAP copy only on a file that appears sparse.
      Sparse files are relatively unusual, and the copying code incurs
      the performance penalty of the now-mandatory sync only for them.

** Portability

  dd once again compiles on AIX 5.1 and 5.2

* Noteworthy changes in release 8.11 (2011-04-13) [stable]

** Bug fixes

  cp -a --link would not create a hardlink to a symlink, instead
  copying the symlink and then not preserving its timestamp.
  [bug introduced in coreutils-8.0]

  cp now avoids FIEMAP issues with BTRFS before Linux 2.6.38,
  which could result in corrupt copies of sparse files.
  [bug introduced in coreutils-8.10]

  cut could segfault when invoked with a user-specified output
  delimiter and an unbounded range like "-f1234567890-".
  [bug introduced in coreutils-5.3.0]

  du would infloop when given --files0-from=DIR
  [bug introduced in coreutils-7.1]

  sort no longer spawns 7 worker threads to sort 16 lines
  [bug introduced in coreutils-8.6]

  touch built on Solaris 9 would segfault when run on Solaris 10
  [bug introduced in coreutils-8.8]

  wc would dereference a NULL pointer upon an early out-of-memory error
  [bug introduced in coreutils-7.1]

** New features

  dd now accepts the 'nocache' flag to the iflag and oflag options,
  which will discard any cache associated with the files, or
  processed portion thereof.

  dd now warns that 'iflag=fullblock' should be used,
  in various cases where partial reads can cause issues.

** Changes in behavior

  cp now avoids syncing files when possible, when doing a FIEMAP copy.
  The sync is only needed on Linux kernels before 2.6.39.
  [The sync was introduced in coreutils-8.10]

  cp now copies empty extents efficiently, when doing a FIEMAP copy.
  It no longer reads the zero bytes from the input, and also can efficiently
  create a hole in the output file when --sparse=always is specified.

  df now aligns columns consistently, and no longer wraps entries
  with longer device identifiers, over two lines.

  install now rejects its long-deprecated --preserve_context option.
  Use --preserve-context instead.

  test now accepts "==" as a synonym for "="

* Noteworthy changes in release 8.10 (2011-02-04) [stable]

** Bug fixes

  du would abort with a failed assertion when two conditions are met:
  part of the hierarchy being traversed is moved to a higher level in the
  directory tree, and there is at least one more command line directory
  argument following the one containing the moved sub-tree.
  [bug introduced in coreutils-5.1.0]

  join --header now skips the ordering check for the first line
  even if the other file is empty.  [bug introduced in coreutils-8.5]

  rm -f no longer fails for EINVAL or EILSEQ on file systems that
  reject file names invalid for that file system.

  uniq -f NUM no longer tries to process fields after end of line.
  [bug introduced in coreutils-7.0]

** New features

  cp now copies sparse files efficiently on file systems with FIEMAP
  support (ext4, btrfs, xfs, ocfs2).  Before, it had to read 2^20 bytes
  when copying a 1MiB sparse file.  Now, it copies bytes only for the
  non-sparse sections of a file.  Similarly, to induce a hole in the
  output file, it had to detect a long sequence of zero bytes.  Now,
  it knows precisely where each hole in an input file is, and can
  reproduce them efficiently in the output file.  mv also benefits
  when it resorts to copying, e.g., between file systems.

  join now supports -o 'auto' which will automatically infer the
  output format from the first line in each file, to ensure
  the same number of fields are output for each line.

** Changes in behavior

  join no longer reports disorder when one of the files is empty.
  This allows one to use join as a field extractor like:
  join -a1 -o 1.3,1.1 - /dev/null

* Noteworthy changes in release 8.9 (2011-01-04) [stable]

** Bug fixes

  split no longer creates files with a suffix length that
  is dependent on the number of bytes or lines per file.
  [bug introduced in coreutils-8.8]

* Noteworthy changes in release 8.8 (2010-12-22) [stable]

** Bug fixes

  cp -u no longer does unnecessary copying merely because the source
  has finer-grained time stamps than the destination.

  od now prints floating-point numbers without losing information, and
  it no longer omits spaces between floating-point columns in some cases.

  sort -u with at least two threads could attempt to read through a
  corrupted pointer. [bug introduced in coreutils-8.6]

  sort with at least two threads and with blocked output would busy-loop
  (spinlock) all threads, often using 100% of available CPU cycles to
  do no work.  I.e., "sort < big-file | less" could waste a lot of power.
  [bug introduced in coreutils-8.6]

  sort with at least two threads no longer segfaults due to use of pointers
  into the stack of an expired thread. [bug introduced in coreutils-8.6]

  sort --compress no longer mishandles subprocesses' exit statuses,
  no longer hangs indefinitely due to a bug in waiting for subprocesses,
  and no longer generates many more than NMERGE subprocesses.

  sort -m -o f f ... f no longer dumps core when file descriptors are limited.

** Changes in behavior

  sort will not create more than 8 threads by default due to diminishing
  performance gains.  Also the --parallel option is no longer restricted
  to the number of available processors.

** New features

  split accepts the --number option to generate a specific number of files.

* Noteworthy changes in release 8.7 (2010-11-13) [stable]

** Bug fixes

  cp, install, mv, and touch no longer crash when setting file times
  on Solaris 10 Update 9 [Solaris PatchID 144488 and newer expose a
  latent bug introduced in coreutils 8.1, and possibly a second latent
  bug going at least as far back as coreutils 5.97]

  csplit no longer corrupts heap when writing more than 999 files,
  nor does it leak memory for every chunk of input processed
  [the bugs were present in the initial implementation]

  tail -F once again notices changes in a currently unavailable
  remote directory [bug introduced in coreutils-7.5]

** Changes in behavior

  cp --attributes-only now completely overrides --reflink.
  Previously a reflink was needlessly attempted.

  stat's %X, %Y, and %Z directives once again print only the integer
  part of seconds since the epoch.  This reverts a change from
  coreutils-8.6, that was deemed unnecessarily disruptive.
  To obtain a nanosecond-precision time stamp for %X use %.X;
  if you want (say) just 3 fractional digits, use %.3X.
  Likewise for %Y and %Z.

  stat's new %W format directive would print floating point seconds.
  However, with the above change to %X, %Y and %Z, we've made %W work
  the same way as the others.

* Noteworthy changes in release 8.6 (2010-10-15) [stable]

** Bug fixes

  du no longer multiply counts a file that is a directory or whose
  link count is 1, even if the file is reached multiple times by
  following symlinks or via multiple arguments.

  du -H and -L now consistently count pointed-to files instead of
  symbolic links, and correctly diagnose dangling symlinks.

  du --ignore=D now ignores directory D even when that directory is
  found to be part of a directory cycle.  Before, du would issue a
  "NOTIFY YOUR SYSTEM MANAGER" diagnostic and fail.

  split now diagnoses read errors rather than silently exiting.
  [bug introduced in coreutils-4.5.8]

  tac would perform a double-free when given an input line longer than 16KiB.
  [bug introduced in coreutils-8.3]

  tail -F once again notices changes in a currently unavailable directory,
  and works around a Linux kernel bug where inotify runs out of resources.
  [bugs introduced in coreutils-7.5]

  tr now consistently handles case conversion character classes.
  In some locales, valid conversion specifications caused tr to abort,
  while in all locales, some invalid specifications were undiagnosed.
  [bugs introduced in coreutils 6.9.90 and 6.9.92]

** New features

  cp now accepts the --attributes-only option to not copy file data,
  which is useful for efficiently modifying files.

  du recognizes -d N as equivalent to --max-depth=N, for compatibility
  with FreeBSD.

  sort now accepts the --debug option, to highlight the part of the
  line significant in the sort, and warn about questionable options.

  sort now supports -d, -f, -i, -R, and -V in any combination.

  stat now accepts the %m format directive to output the mount point
  for a file.  It also accepts the %w and %W format directives for
  outputting the birth time of a file, if one is available.

** Changes in behavior

  df now consistently prints the device name for a bind mounted file,
  rather than its aliased target.

  du now uses less than half as much memory when operating on trees
  with many hard-linked files.  With --count-links (-l), or when
  operating on trees with no hard-linked files, there is no change.

  ls -l now uses the traditional three field time style rather than
  the wider two field numeric ISO style, in locales where a style has
  not been specified.  The new approach has nicer behavior in some
  locales, including English, which was judged to outweigh the disadvantage
  of generating less-predictable and often worse output in poorly-configured
  locales where there is an onus to specify appropriate non-default styles.
  [The old behavior was introduced in coreutils-6.0 and had been removed
   for English only using a different method since coreutils-8.1]

  rm's -d now evokes an error;  before, it was silently ignored.

  sort -g now uses long doubles for greater range and precision.

  sort -h no longer rejects numbers with leading or trailing ".", and
  no longer accepts numbers with multiple ".".  It now considers all
  zeros to be equal.

  sort now uses the number of available processors to parallelize
  the sorting operation.  The number of sorts run concurrently can be
  limited with the --parallel option or with external process
  control like taskset for example.

  stat now provides translated output when no format is specified.

  stat no longer accepts the --context (-Z) option.  Initially it was
  merely accepted and ignored, for compatibility.  Starting two years
  ago, with coreutils-7.0, its use evoked a warning.  Printing the
  SELinux context of a file can be done with the %C format directive,
  and the default output when no format is specified now automatically
  includes %C when context information is available.

  stat no longer accepts the %C directive when the --file-system
  option is in effect, since security context is a file attribute
  rather than a file system attribute.

  stat now outputs the full sub-second resolution for the atime,
  mtime, and ctime values since the Epoch, when using the %X, %Y, and
  %Z directives of the --format option.  This matches the fact that
  %x, %y, and %z were already doing so for the human-readable variant.

  touch's --file option is no longer recognized.  Use --reference=F (-r)
  instead.  --file has not been documented for 15 years, and its use has
  elicited a warning since coreutils-7.1.

  truncate now supports setting file sizes relative to a reference file.
  Also errors are no longer suppressed for unsupported file types, and
  relative sizes are restricted to supported file types.

* Noteworthy changes in release 8.5 (2010-04-23) [stable]

** Bug fixes

  cp and mv once again support preserving extended attributes.
  [bug introduced in coreutils-8.4]

  cp now preserves "capabilities" when also preserving file ownership.

  ls --color once again honors the 'NORMAL' dircolors directive.
  [bug introduced in coreutils-6.11]

  sort -M now handles abbreviated months that are aligned using blanks
  in the locale database.  Also locales with 8 bit characters are
  handled correctly, including multi byte locales with the caveat
  that multi byte characters are matched case sensitively.

  sort again handles obsolescent key formats (+POS -POS) correctly.
  Previously if -POS was specified, 1 field too many was used in the sort.
  [bug introduced in coreutils-7.2]

** New features

  join now accepts the --header option, to treat the first line of each
  file as a header line to be joined and printed unconditionally.

  timeout now accepts the --kill-after option which sends a kill
  signal to the monitored command if it's still running the specified
  duration after the initial signal was sent.

  who: the "+/-" --mesg (-T) indicator of whether a user/tty is accepting
  messages could be incorrectly listed as "+", when in fact, the user was
  not accepting messages (mesg no).  Before, who would examine only the
  permission bits, and not consider the group of the TTY device file.
  Thus, if a login tty's group would change somehow e.g., to "root",
  that would make it unwritable (via write(1)) by normal users, in spite
  of whatever the permission bits might imply.  Now, when configured
  using the --with-tty-group[=NAME] option, who also compares the group
  of the TTY device with NAME (or "tty" if no group name is specified).

** Changes in behavior

  ls --color no longer emits the final 3-byte color-resetting escape
  sequence when it would be a no-op.

  join -t '' no longer emits an error and instead operates on
  each line as a whole (even if they contain NUL characters).

* Noteworthy changes in release 8.4 (2010-01-13) [stable]

** Bug fixes

  nproc --all is now guaranteed to be as large as the count
  of available processors, which may not have been the case
  on GNU/Linux systems with neither /proc nor /sys available.
  [bug introduced in coreutils-8.1]

** Build-related

  Work around a build failure when using buggy <sys/capability.h>.
  Alternatively, configure with --disable-libcap.

  Compilation would fail on systems using glibc-2.7..2.9 due to changes in
  gnulib's wchar.h that tickled a bug in at least those versions of glibc's
  own <wchar.h> header.  Now, gnulib works around the bug in those older
  glibc <wchar.h> headers.

  Building would fail with a link error (cp/copy.o) when XATTR headers
  were installed without the corresponding library.  Now, configure
  detects that and disables xattr support, as one would expect.

* Noteworthy changes in release 8.3 (2010-01-07) [stable]

** Bug fixes

  cp -p, install -p, mv, and touch -c could trigger a spurious error
  message when using new glibc coupled with an old kernel.
  [bug introduced in coreutils-6.12].

  ls -l --color no longer prints "argetm" in front of dangling
  symlinks when the 'LINK target' directive was given to dircolors.
  [bug introduced in fileutils-4.0]

  pr's page header was improperly formatted for long file names.
  [bug introduced in coreutils-7.2]

  rm -r --one-file-system works once again.
  The rewrite to make rm use fts introduced a regression whereby
  a commmand of the above form would fail for all subdirectories.
  [bug introduced in coreutils-8.0]

  stat -f recognizes more file system types: k-afs, fuseblk, gfs/gfs2, ocfs2,
  and rpc_pipefs. Also Minix V3 is displayed correctly as minix3, not minux3.
  [bug introduced in coreutils-8.1]

  tail -f (inotify-enabled) once again works with remote files.
  The use of inotify with remote files meant that any changes to those
  files that was not done from the local system would go unnoticed.
  [bug introduced in coreutils-7.5]

  tail -F (inotify-enabled) would abort when a tailed file is repeatedly
  renamed-aside and then recreated.
  [bug introduced in coreutils-7.5]

  tail -F (inotify-enabled) could fail to follow renamed files.
  E.g., given a "tail -F a b" process, running "mv a b" would
  make tail stop tracking additions to "b".
  [bug introduced in coreutils-7.5]

  touch -a and touch -m could trigger bugs in some file systems, such
  as xfs or ntfs-3g, and fail to update timestamps.
  [bug introduced in coreutils-8.1]

  wc now prints counts atomically so that concurrent
  processes will not intersperse their output.
  [the issue dates back to the initial implementation]

* Noteworthy changes in release 8.2 (2009-12-11) [stable]

** Bug fixes

  id's use of mgetgroups no longer writes beyond the end of a malloc'd buffer
  [bug introduced in coreutils-8.1]

  id no longer crashes on systems without supplementary group support.
  [bug introduced in coreutils-8.1]

  rm once again handles zero-length arguments properly.
  The rewrite to make rm use fts introduced a regression whereby
  a command like "rm a '' b" would fail to remove "a" and "b", due to
  the presence of the empty string argument.
  [bug introduced in coreutils-8.0]

  sort is now immune to the signal handling of its parent.
  Specifically sort now doesn't exit with an error message
  if it uses helper processes for compression and its parent
  ignores CHLD signals. [bug introduced in coreutils-6.9]

  tail without -f no longer accesses uninitialized memory
  [bug introduced in coreutils-7.6]

  timeout is now immune to the signal handling of its parent.
  Specifically timeout now doesn't exit with an error message
  if its parent ignores CHLD signals. [bug introduced in coreutils-7.6]

  a user running "make distcheck" in the coreutils source directory,
  with TMPDIR unset or set to the name of a world-writable directory,
  and with a malicious user on the same system
  was vulnerable to arbitrary code execution
  [bug introduced in coreutils-5.0]

* Noteworthy changes in release 8.1 (2009-11-18) [stable]

** Bug fixes

  chcon no longer exits immediately just because SELinux is disabled.
  Even then, chcon may still be useful.
  [bug introduced in coreutils-8.0]

  chcon, chgrp, chmod, chown and du now diagnose an ostensible directory cycle
  and arrange to exit nonzero.  Before, they would silently ignore the
  offending directory and all "contents."

  env -u A=B now fails, rather than silently adding A to the
  environment.  Likewise, printenv A=B silently ignores the invalid
  name.  [the bugs date back to the initial implementation]

  ls --color now handles files with capabilities correctly.  Previously
  files with capabilities were often not colored, and also sometimes, files
  without capabilites were colored in error. [bug introduced in coreutils-7.0]

  md5sum now prints checksums atomically so that concurrent
  processes will not intersperse their output.
  This also affected sum, sha1sum, sha224sum, sha384sum and sha512sum.
  [the bug dates back to the initial implementation]

  mktemp no longer leaves a temporary file behind if it was unable to
  output the name of the file to stdout.
  [the bug dates back to the initial implementation]

  nice -n -1 PROGRAM now runs PROGRAM even when its internal setpriority
  call fails with errno == EACCES.
  [the bug dates back to the initial implementation]

  nice, nohup, and su now refuse to execute the subsidiary program if
  they detect write failure in printing an otherwise non-fatal warning
  message to stderr.

  stat -f recognizes more file system types: afs, cifs, anon-inode FS,
  btrfs, cgroupfs, cramfs-wend, debugfs, futexfs, hfs, inotifyfs, minux3,
  nilfs, securityfs, selinux, xenfs

  tail -f (inotify-enabled) now avoids a race condition.
  Before, any data appended in the tiny interval between the initial
  read-to-EOF and the inotify watch initialization would be ignored
  initially (until more data was appended), or forever, if the file
  were first renamed or unlinked or never modified.
  [The race was introduced in coreutils-7.5]

  tail -F (inotify-enabled) now consistently tails a file that has been
  replaced via renaming.  That operation provokes either of two sequences
  of inotify events.  The less common sequence is now handled as well.
  [The bug came with the implementation change in coreutils-7.5]

  timeout now doesn't exit unless the command it is monitoring does,
  for any specified signal. [bug introduced in coreutils-7.0].

** Changes in behavior

  chroot, env, nice, and su fail with status 125, rather than 1, on
  internal error such as failure to parse command line arguments; this
  is for consistency with stdbuf and timeout, and avoids ambiguity
  with the invoked command failing with status 1.  Likewise, nohup
  fails with status 125 instead of 127.

  du (due to a change in gnulib's fts) can now traverse NFSv4 automounted
  directories in which the stat'd device number of the mount point differs
  during a traversal.  Before, it would fail, because such a mismatch would
  usually represent a serious error or a subversion attempt.

  echo and printf now interpret \e as the Escape character (0x1B).

  rm -f /read-only-fs/nonexistent now succeeds and prints no diagnostic
  on systems with an unlinkat syscall that sets errno to EROFS in that case.
  Before, it would fail with a "Read-only file system" diagnostic.
  Also, "rm /read-only-fs/nonexistent" now reports "file not found" rather
  than the less precise "Read-only file system" error.

** New programs

  nproc: Print the number of processing units available to a process.

** New features

  env and printenv now accept the option --null (-0), as a means to
  avoid ambiguity with newlines embedded in the environment.

  md5sum --check now also accepts openssl-style checksums.
  So do sha1sum, sha224sum, sha384sum and sha512sum.

  mktemp now accepts the option --suffix to provide a known suffix
  after the substitution in the template.  Additionally, uses such as
  "mktemp fileXXXXXX.txt" are able to infer an appropriate --suffix.

  touch now accepts the option --no-dereference (-h), as a means to
  change symlink timestamps on platforms with enough support.

* Noteworthy changes in release 8.0 (2009-10-06) [beta]

** Bug fixes

  cp --preserve=xattr and --archive now preserve extended attributes even
  when the source file doesn't have write access.
  [bug introduced in coreutils-7.1]

  touch -t [[CC]YY]MMDDhhmm[.ss] now accepts a timestamp string ending in .60,
  to accommodate leap seconds.
  [the bug dates back to the initial implementation]

  ls --color now reverts to the color of a base file type consistently
  when the color of a more specific type is disabled.
  [bug introduced in coreutils-5.90]

  ls -LR exits with status 2, not 0, when it encounters a cycle

  "ls -is" is now consistent with ls -lis in ignoring values returned
  from a failed stat/lstat.  For example ls -Lis now prints "?", not "0",
  for the inode number and allocated size of a dereferenced dangling symlink.

  tail --follow --pid now avoids a race condition where data written
  just before the process dies might not have been output by tail.
  Also, tail no longer delays at all when the specified pid is not live.
  [The race was introduced in coreutils-7.5,
   and the unnecessary delay was present since textutils-1.22o]

** Portability

  On Solaris 9, many commands would mistakenly treat file/ the same as
  file.  Now, even on such a system, path resolution obeys the POSIX
  rules that a trailing slash ensures that the preceeding name is a
  directory or a symlink to a directory.

** Changes in behavior

  id no longer prints SELinux " context=..." when the POSIXLY_CORRECT
  environment variable is set.

  readlink -f now ignores a trailing slash when deciding if the
  last component (possibly via a dangling symlink) can be created,
  since mkdir will succeed in that case.

** New features

  ln now accepts the options --logical (-L) and --physical (-P),
  added by POSIX 2008.  The default behavior is -P on systems like
  GNU/Linux where link(2) creates hard links to symlinks, and -L on
  BSD systems where link(2) follows symlinks.

  stat: without -f, a command-line argument of "-" now means standard input.
  With --file-system (-f), an argument of "-" is now rejected.
  If you really must operate on a file named "-", specify it as
  "./-" or use "--" to separate options from arguments.

** Improvements

  rm: rewrite to use gnulib's fts
  This makes rm -rf significantly faster (400-500%) in some pathological
  cases, and slightly slower (20%) in at least one pathological case.

  rm -r deletes deep hierarchies more efficiently.  Before, execution time
  was quadratic in the depth of the hierarchy, now it is merely linear.
  However, this improvement is not as pronounced as might be expected for
  very deep trees, because prior to this change, for any relative name
  length longer than 8KiB, rm -r would sacrifice official conformance to
  avoid the disproportionate quadratic performance penalty.  Leading to
  another improvement:

  rm -r is now slightly more standards-conformant when operating on
  write-protected files with relative names longer than 8KiB.

* Noteworthy changes in release 7.6 (2009-09-11) [stable]

** Bug fixes

  cp, mv now ignore failure to preserve a symlink time stamp, when it is
  due to their running on a kernel older than what was implied by headers
  and libraries tested at configure time.
  [bug introduced in coreutils-7.5]

  cp --reflink --preserve now preserves attributes when cloning a file.
  [bug introduced in coreutils-7.5]

  cp --preserve=xattr no longer leaks resources on each preservation failure.
  [bug introduced in coreutils-7.1]

  dd now exits with non-zero status when it encounters a write error while
  printing a summary to stderr.
  [bug introduced in coreutils-6.11]

  dd cbs=N conv=unblock would fail to print a final newline when the size
  of the input was not a multiple of N bytes.
  [the non-conforming behavior dates back to the initial implementation]

  df no longer requires that each command-line argument be readable
  [bug introduced in coreutils-7.3]

  ls -i now prints consistent inode numbers also for mount points.
  This makes ls -i DIR less efficient on systems with dysfunctional readdir,
  because ls must stat every file in order to obtain a guaranteed-valid
  inode number.  [bug introduced in coreutils-6.0]

  tail -f (inotify-enabled) now flushes any initial output before blocking.
  Before, this would print nothing and wait: stdbuf -o 4K tail -f /etc/passwd
  Note that this bug affects tail -f only when its standard output is buffered,
  which is relatively unusual.
  [bug introduced in coreutils-7.5]

  tail -f once again works with standard input.  inotify-enabled tail -f
  would fail when operating on a nameless stdin.  I.e., tail -f < /etc/passwd
  would say "tail: cannot watch `-': No such file or directory", yet the
  relatively baroque tail -f /dev/stdin < /etc/passwd would work.  Now, the
  offending usage causes tail to revert to its conventional sleep-based
  (i.e., not inotify-based) implementation.
  [bug introduced in coreutils-7.5]

** Portability

  ln, link: link f z/ would mistakenly succeed on Solaris 10, given an
  existing file, f, and nothing named "z".  ln -T f z/ has the same problem.
  Each would mistakenly create "z" as a link to "f".  Now, even on such a
  system, each command reports the error, e.g.,
  link: cannot create link `z/' to `f': Not a directory

** New features

  cp --reflink accepts a new "auto" parameter which falls back to
  a standard copy if creating a copy-on-write clone is not possible.

** Changes in behavior

  tail -f now ignores "-" when stdin is a pipe or FIFO.
  tail-with-no-args now ignores -f unconditionally when stdin is a pipe or FIFO.
  Before, it would ignore -f only when no file argument was specified,
  and then only when POSIXLY_CORRECT was set.  Now, :|tail -f - terminates
  immediately.  Before, it would block indefinitely.

* Noteworthy changes in release 7.5 (2009-08-20) [stable]

** Bug fixes

  dd's oflag=direct option now works even when the size of the input
  is not a multiple of e.g., 512 bytes.

  dd now handles signals consistently even when they're received
  before data copying has started.

  install runs faster again with SELinux enabled
  [introduced in coreutils-7.0]

  ls -1U (with two or more arguments, at least one a nonempty directory)
  would print entry names *before* the name of the containing directory.
  Also fixed incorrect output of ls -1RU and ls -1sU.
  [introduced in coreutils-7.0]

  sort now correctly ignores fields whose ending position is specified
  before the start position. Previously in numeric mode the remaining
  part of the line after the start position was used as the sort key.
  [This bug appears to have been present in "the beginning".]

  truncate -s failed to skip all whitespace in the option argument in
  some locales.

** New programs

  stdbuf: A new program to run a command with modified stdio buffering
  for its standard streams.

** Changes in behavior

  ls --color: files with multiple hard links are no longer colored differently
  by default. That can be enabled by changing the LS_COLORS environment
  variable. You can control that using the MULTIHARDLINK dircolors input
  variable which corresponds to the 'mh' LS_COLORS item. Note these variables
  were renamed from 'HARDLINK' and 'hl' which were available since
  coreutils-7.1 when this feature was introduced.

** Deprecated options

  nl --page-increment: deprecated in favor of --line-increment, the new option
  maintains the previous semantics and the same short option, -i.

** New features

  chroot now accepts the options --userspec and --groups.

  cp accepts a new option, --reflink: create a lightweight copy
  using copy-on-write (COW).  This is currently only supported within
  a btrfs file system.

  cp now preserves time stamps on symbolic links, when possible

  sort accepts a new option, --human-numeric-sort (-h): sort numbers
  while honoring human readable suffixes like KiB and MB etc.

  tail --follow now uses inotify when possible, to be more responsive
  to file changes and more efficient when monitoring many files.

* Noteworthy changes in release 7.4 (2009-05-07) [stable]

** Bug fixes

  date -d 'next mon', when run on a Monday, now prints the date
  7 days in the future rather than the current day.  Same for any other
  day-of-the-week name, when run on that same day of the week.
  [This bug appears to have been present in "the beginning". ]

  date -d tuesday, when run on a Tuesday -- using date built from the 7.3
  release tarball, not from git -- would print the date 7 days in the future.
  Now, it works properly and prints the current date.  That was due to
  human error (including not-committed changes in a release tarball)
  and the fact that there is no check to detect when the gnulib/ git
  submodule is dirty.

** Build-related

  make check: two tests have been corrected

** Portability

  There have been some ACL-related portability fixes for *BSD,
  inherited from gnulib.

* Noteworthy changes in release 7.3 (2009-05-01) [stable]

** Bug fixes

  cp now diagnoses failure to preserve selinux/xattr attributes when
  --preserve=context,xattr is specified in combination with -a.
  Also, cp no longer suppresses attribute-preservation diagnostics
  when preserving SELinux context was explicitly requested.

  ls now aligns output correctly in the presence of abbreviated month
  names from the locale database that have differing widths.

  ls -v and sort -V now order names like "#.b#" properly

  mv: do not print diagnostics when failing to preserve xattr's on file
  systems without xattr support.

  sort -m no longer segfaults when its output file is also an input file.
  E.g., with this, touch 1; sort -m -o 1 1, sort would segfault.
  [introduced in coreutils-7.2]

** Changes in behavior

  shred, sort, shuf: now use an internal pseudorandom generator by default.
  This is mainly noticable in shred where the 3 random passes it does by
  default should proceed at the speed of the disk.  Previously /dev/urandom
  was used if available, which is relatively slow on GNU/Linux systems.

** Improved robustness

  cp would exit successfully after copying less than the full contents
  of a file larger than ~4000 bytes from a linux-/proc file system to a
  destination file system with a fundamental block size of 4KiB or greater.
  Reading into a 4KiB-or-larger buffer, cp's "read" syscall would return
  a value smaller than 4096, and cp would interpret that as EOF (POSIX
  allows this).  This optimization, now removed, saved 50% of cp's read
  syscalls when copying small files.  Affected linux kernels: at least
  2.6.9 through 2.6.29.
  [the optimization was introduced in coreutils-6.0]

** Portability

  df now pre-mounts automountable directories even with automounters for
  which stat-like syscalls no longer provoke mounting.  Now, df uses open.

  `id -G $USER` now works correctly even on Darwin and NetBSD. Previously it
  would either truncate the group list to 10, or go into an infinite loop,
  due to their non-standard getgrouplist implementations.
  [truncation introduced in coreutils-6.11]
  [infinite loop introduced in coreutils-7.1]

* Noteworthy changes in release 7.2 (2009-03-31) [stable]

** New features

  pwd now accepts the options --logical (-L) and --physical (-P).  For
  compatibility with existing scripts, -P is the default behavior
  unless POSIXLY_CORRECT is requested.

** Bug fixes

  cat once again immediately outputs data it has processed.
  Previously it would have been buffered and only output if enough
  data was read, or on process exit.
  [bug introduced in coreutils-6.0]

  comm's new --check-order option would fail to detect disorder on any pair
  of lines where one was a prefix of the other.  For example, this would
  fail to report the disorder: printf 'Xb\nX\n'>k; comm --check-order k k
  [bug introduced in coreutils-7.0]

  cp once again diagnoses the invalid "cp -rl dir dir" right away,
  rather than after creating a very deep dir/dir/dir/... hierarchy.
  The bug strikes only with both --recursive (-r, -R) and --link (-l).
  [bug introduced in coreutils-7.1]

  ls --sort=version (-v) sorted names beginning with "." inconsistently.
  Now, names that start with "." are always listed before those that don't.

  pr: fix the bug whereby --indent=N (-o) did not indent header lines
  [bug introduced in coreutils-6.9.90]

  sort now handles specified key ends correctly.
  Previously -k1,1b would have caused leading space from field 2 to be
  included in the sort while -k2,3.0 would have not included field 3.

** Changes in behavior

  cat,cp,install,mv,split: these programs now read and write a minimum
  of 32KiB at a time.  This was seen to double throughput when reading
  cached files on GNU/Linux-based systems.

  cp -a now tries to preserve extended attributes (xattr), but does not
  diagnose xattr-preservation failure.  However, cp --preserve=all still does.

  ls --color: hard link highlighting can be now disabled by changing the
  LS_COLORS environment variable. To disable it you can add something like
  this to your profile: eval `dircolors | sed s/hl=[^:]*:/hl=:/`

* Noteworthy changes in release 7.1 (2009-02-21) [stable]

** New features

  Add extended attribute support available on certain filesystems like ext2
  and XFS.
    cp: Tries to copy xattrs when --preserve=xattr or --preserve=all specified
    mv: Always tries to copy xattrs
    install: Never copies xattrs

  cp and mv accept a new option, --no-clobber (-n): silently refrain
  from overwriting any existing destination file

  dd accepts iflag=cio and oflag=cio to open the file in CIO (concurrent I/O)
  mode where this feature is available.

  install accepts a new option, --compare (-C): compare each pair of source
  and destination files, and if the destination has identical content and
  any specified owner, group, permissions, and possibly SELinux context, then
  do not modify the destination at all.

  ls --color now highlights hard linked files, too

  stat -f recognizes the Lustre file system type

** Bug fixes

  chgrp, chmod, chown --silent (--quiet, -f) no longer print some diagnostics
  [bug introduced in coreutils-5.1]

  cp uses much less memory in some situations

  cp -a now correctly tries to preserve SELinux context (announced in 6.9.90),
  doesn't inform about failure, unlike with --preserve=all

  du --files0-from=FILE no longer reads all of FILE into RAM before
  processing the first file name

  seq 9223372036854775807 9223372036854775808 now prints only two numbers
  on systems with extended long double support and good library support.
  Even with this patch, on some systems, it still produces invalid output,
  from 3 to at least 1026 lines long. [bug introduced in coreutils-6.11]

  seq -w now accounts for a decimal point added to the last number
  to correctly print all numbers to the same width.

  wc --files0-from=FILE no longer reads all of FILE into RAM, before
  processing the first file name, unless the list of names is known
  to be small enough.

** Changes in behavior

  cp and mv: the --reply={yes,no,query} option has been removed.
  Using it has elicited a warning for the last three years.

  dd: user specified offsets that are too big are handled better.
  Previously, erroneous parameters to skip and seek could result
  in redundant reading of the file with no warnings or errors.

  du: -H (initially equivalent to --si) is now equivalent to
  --dereference-args, and thus works as POSIX requires

  shred: now does 3 overwrite passes by default rather than 25.

  ls -l now marks SELinux-only files with the less obtrusive '.',
  rather than '+'.  A file with any other combination of MAC and ACL
  is still marked with a '+'.

* Noteworthy changes in release 7.0 (2008-10-05) [beta]

** New programs

  timeout: Run a command with bounded time.
  truncate: Set the size of a file to a specified size.

** New features

  chgrp, chmod, chown, chcon, du, rm: now all display linear performance,
  even when operating on million-entry directories on ext3 and ext4 file
  systems.  Before, they would exhibit O(N^2) performance, due to linear
  per-entry seek time cost when operating on entries in readdir order.
  Rm was improved directly, while the others inherit the improvement
  from the newer version of fts in gnulib.

  comm now verifies that the inputs are in sorted order.  This check can
  be turned off with the --nocheck-order option.

  comm accepts new option, --output-delimiter=STR, that allows specification
  of an output delimiter other than the default single TAB.

  cp and mv: the deprecated --reply=X option is now also undocumented.

  dd accepts iflag=fullblock to make it accumulate full input blocks.
  With this new option, after a short read, dd repeatedly calls read,
  until it fills the incomplete block, reaches EOF, or encounters an error.

  df accepts a new option --total, which produces a grand total of all
  arguments after all arguments have been processed.

  If the GNU MP library is available at configure time, factor and
  expr support arbitrarily large numbers.  Pollard's rho algorithm is
  used to factor large numbers.

  install accepts a new option --strip-program to specify the program used to
  strip binaries.

  ls now colorizes files with capabilities if libcap is available

  ls -v now uses filevercmp function as sort predicate (instead of strverscmp)

  md5sum now accepts the new option, --quiet, to suppress the printing of
  'OK' messages.  sha1sum, sha224sum, sha384sum, and sha512sum accept it, too.

  sort accepts a new option, --files0-from=F, that specifies a file
  containing a null-separated list of files to sort.  This list is used
  instead of filenames passed on the command-line to avoid problems with
  maximum command-line (argv) length.

  sort accepts a new option --batch-size=NMERGE, where NMERGE
  represents the maximum number of inputs that will be merged at once.
  When processing more than NMERGE inputs, sort uses temporary files.

  sort accepts a new option --version-sort (-V, --sort=version),
  specifying that ordering is to be based on filevercmp.

** Bug fixes

  chcon --verbose now prints a newline after each message

  od no longer suffers from platform bugs in printf(3).  This is
  probably most noticeable when using 'od -tfL' to print long doubles.

  seq -0.1 0.1 2 now prints 2,0 when locale's decimal point is ",".
  Before, it would mistakenly omit the final number in that example.

  shuf honors the --zero-terminated (-z) option, even with --input-range=LO-HI

  shuf --head-count is now correctly documented.  The documentation
  previously claimed it was called --head-lines.

** Improvements

  Improved support for access control lists (ACLs): On MacOS X, Solaris 7..10,
  HP-UX 11, Tru64, AIX, IRIX 6.5, and Cygwin, "ls -l" now displays the presence
  of an ACL on a file via a '+' sign after the mode, and "cp -p" copies ACLs.

  join has significantly better performance due to better memory management

  ls now uses constant memory when not sorting and using one_per_line format,
  no matter how many files are in a given directory.  I.e., to list a directory
  with very many files, ls -1U is much more efficient.

  od now aligns fields across lines when printing multiple -t
  specifiers, and no longer prints fields that resulted entirely from
  padding the input out to the least common multiple width.

** Changes in behavior

  stat's --context (-Z) option has always been a no-op.
  Now it evokes a warning that it is obsolete and will be removed.
