Backed out most of rev.1.4. I didn't submit it; I only submitted a

request for it something like it.  It was poorly worded and too
far from both POSIX wording and normal (mal)practice by referring to
sysconf(_SC_NGROUPS_MAX) instead of {NGROUPS_MAX} or NGROUPS.  POSIX.1
uses curly braces to mark up "symbolic constants or limits [that may
be] defined in certain headers".  Since we don't document this markup,
don't use it.  Just use NGROUPS_MAX.
