to the id_print() function.
Use getgrouplist(3) for the case when an user was specified,
and getgroups(2) when no user was given.
That reverts to the expected behaviour and makes it easy to
implement an option later to force using getgrouplist(3).
NGROUPS groups. getgrouplist(3) may put a duplicate group
id into the passed array (it sets [0] and [1] to the value
of the gid argument), but id_print() sorts them out.
Showing the ids of both an user given by an argument to `id',
and the current user, is now handled in a single function.
Displaying the current user's ids was inaccurate because
getgroups(2) had been used. getgroups(2) returns the current
kernel state of a user's groups, which may not always be
correct if /etc/group was recently changed.
