Log Message:
Update to 1.4.7:

Version 1.4.7 - 25 September 2006, by Eric Blake  (CVS version 1.4.6a)

* Fix regression from 1.4.5 in handling a file that ends in a macro
  expansion without arguments instead of a newline.
* The define and pushdef macros now warn when the first argument is not
  a string, rather than silently doing nothing.
* Standard input can now be read more than once, as in 'm4 - file -', and
  is not closed until all wrapped text is handled.  This makes a
  difference when stdin is not a regular file, and also fixes bugs when
  using the syscmd or esyscmd macros from wrapped text.
* When standard input is a seekable file, the m4exit, syscmd, and esyscmd
  macros now restore the current position to the next unread byte rather
  than discarding an arbitrary amount of buffered data.
* SysV command-line compatibility is no longer a goal of GNU M4; the
  focus will be instead on POSIX compatibility.  This release continues to
  support previous usage, but adds warnings in areas which will allow a
  future version of GNU M4 to use its own extensions without being tied to
  the SysV command line interface.
* The no-op compatibility command line options -B, -N, -S, -T, and
  --diversions may be withdrawn or assigned new meanings in future
  releases, so they now issue a warning if used.
* A new command line option -i replaces the compatibility -e as the
  short spelling of --interactive, for consistency with other GNU tools; a
  warning is issued if the old spelling is used, and it may be assigned new
  meaning in future releases.
* A new command line option --debugfile replaces the options -o and
  --error-output as the preferred spelling.  The old options were
  misleading in their names and inconsistent with other GNU tools; they are
  still silently accepted, but no longer documented in --help, and may be
  assigned new meanings in future releases.
