Hi Eggert,
Thanks for fixing that!

Exactly, using the current sources it does that.  But I thought that by
installing a patch similar to that diff you just sent that change would
have to be explicitly made, something like (grp == NULL && just_group),
but I had never looked at the coreutils code, was just trying to make a
good proposion of my desired behavior and ideas.  I did a quick reading
now and noticed that `print_group' takes care of that cases.  Perfect!

Two questions now:
1. I see your code isn't applied directly to savannah's repository.
   Is there an alternative repository?
   BTW, today apparently some modules of the server are "broken", there's
   some modules that we just can't check out, including coreutils.  I was
   reading the code via ViewCVS.
2. You're certainly an authoritative person to answer this question:
   Why the Standards doesn't specify exactly the return codes, at least
   for the most common cases, for the applications?  Whouldn't that be
   easier to make some decisions?

Thanks,
