Summary: fix test_grp failing on RedHat 6.2

Initial Comment:
I didn't really think this should go into 2.3, but I'll
let you make the decision.  This patch fixes the
test_grp failure on RedHat 6.2/Alpha (asmodean) in the
snake-farm.  I thought it was specific to RH 6.2,
apparently it's not.  If you add a + as the last line
in /etc/group the test will fail on RH 9 too.

Walter Doerwald may know more about how best to fix
this.  I'm not certain if it's really a problem in the
extension module or the test.
If you want to fix the test, the patch is included here:

     def check_value(self, value):
         # check that a grp tuple has the entries and
         # attributes promised by the docs
+        if value == ('+', None, 0, []):
+            # some libc's return the last line of +
+            return

The '+ ...' line at the end of the /etc/passwd file tells
the system to also pickup information from the appropriate
map in LDAP, or NIS (yellow pages).  See also section 7.2 on
this page:

I don't recall what the + is for either.  Does it have
something to do with YP/NIS?  I don't think this is really
critical so I'm droping the priority.  If  pwdmodule.c is
changed, it will be an interface change so it's questionable
for 2.3.1.

This was found on the snake farm, never reported by a user.

pwdmodule.c hasn't changed in 7 months, so I'd say this is a
problem with the test. But ('+', None, 0, []) doesn't seem
to be a valid entry, so (although it's not a bug in Python)
maybe Python should hide this entry.

Remind me what + on a line means in /etc/group.  "man group"
on RH9 gives no clue.  I'm still nervous about it, can we
defer until 2.3.1?
