I am posting this to Brian Fox since I can't seem to reach him via mail.
I have tried a couple of different mail addresses with no luck.
(The aurel.cns.caltech.edu address is the address that was embedded
in the mail that I got from you, Brian.)

Brian,  this is what I get when I try to mail to you.

Anyway, the problem I found has apparently been fixed and diffs have been sent
to you by Chet Ramey.  Greg Onufer discovered that the actual problem
was in the way bash dealt with variables such as ${1}.  The script that
failed had the following in it:

exec /bin/expr "/${1:-.}" ......

It appears that $1 is not being expanded (is null), so a "." is returned.
If you need anything else, let me know.

Thanks for all the hard work you have done.  1.04 works marvelously on
Interactive's 386ix.

Keep up the good work!
        Don
