I'm using ar(1) to make an archive of program sources, for an interpreter
that works best searching such archives.  Of 800-some-odd programs, one
causes ar(1) to choke and foul up.

I'm running 3.51, using the new archive stuff.

Does anyone have the slightest idea what it is about this one file that
makes ar start acting so weird?  I'm inclosing a shar of 2 of the files.
FSE2K.m is the culprit.  It's 16 bytes long, and like all of the files,
it is pure printable ASCII.  I don't even think they have TAB characters.

Fortunately, as you'll see from the contents of the file, it is dispensable
and exists just to explain a (possible) error message when running the
programs.  I will dispense with it, but such things worry me.

To get the problem I have been seeing, unshar the stuff below, and do

	ar qv ARCHIVE *.m

It should complain of a badly formed archive.  You also get errors on
using a key of rv.

#! /bin/sh
# This is a shell archive.  Remove anything before this line, then unpack
# it by saving it into a file and typing "sh file".  To overwrite existing
# files, type "sh file -c".  You can also feed this as standard input via
# unshar, or by typing "sh <file", e.g..  If this archive is complete, you
# will see the following message at the end:
#		"End of shell archive."
# Contents:  A.m FSE2K.m
