# We have to find a command that prints all (effective
# and real) group names (not ids).  The known commands are:
# groups
# id -Gn
# id -a
# Beware 1: some systems do just 'id -G' even when 'id -Gn' is used.
# Beware 2: id -Gn or id -a format might be id(name) or name(id).
# Beware 3: the groups= might be anywhere in the id output.
# Beware 4: groups can have spaces ('id -a' being the only defense against this)
# Beware 5: id -a might not contain the groups= part.
#
# That is, we might meet the following:
#
# foo bar zot				# accept
# foo 22 42 bar zot			# accept
# 1 22 42 2 3				# reject
# groups=(42),foo(1),bar(2),zot me(3)	# parse
# groups=22,42,1(foo),2(bar),3(zot me)	# parse
#
# and the groups= might be after, before, or between uid=... and gid=...
