System: NetBSD sopwith 1.3.3 NetBSD 1.3.3 (GENERIC) #7: Fri Dec 11 21:32:58 PST 1998 ross@zeta:/usr/src/sys/arch/alpha/compile/GENERIC alpha


>Description:
	From the mtree(8) man page:

Empty lines and lines whose first non-whitespace character is a hash mark
     (``#'') are ignored.

This results in incorrect behaviour if filenames begin with '#'.
Mtree then reports the '#' file as being "extra".
If the filename is long enough for mtree -c to split the output
line, even more bogus errors are reported.

This happens on both 1.3.3 and 1.4.

In addition to the '#' problem, I also observe incorrect complaints
about flags not matching when they should.  I haven't been able to
generate a demo from scratch, but here is an example:

machtoo ls -lao
total 2
drwxr-xr-x   2 root  wheel  -  512 Dec 29  1997 .
drwxr-xr-x  21 root  wheel  - 1024 Feb  6  1998 ..
machtoo mtree -c | mtree
.:      flags ("none" is not "none")
machtoo mtree -c        
#          user: snoopy
#       machine: machtoo.uucp
#          tree: /a/home
#          date: Sat May 29 11:21:39 1999

# .
.               type=dir mode=0755 nlink=2 time=883450272.0 flags=none
machtoo 


>How-To-Repeat:

    foo         size=0 time=927999835.137695000
machtoo        


>Fix:
	

I suggest having mtree only treat '#' as a comment when it appears at
the very beginning of a line, without whitespace.
