description:
make(1): require argument of Lst_Member to be non-null
Since the lists don't contain null pointers, it doesn't make sense to
search for a null pointer. All calls but one already had obviously
non-null arguments. The one remaining call using targ->suff has been
guarded for now.
The code for Lst_Member became much simpler than before. Partly because
the old code had an extra condition for circular lists, which are not
used by make.
