I agree. And we might as well also document what happens when
zero is passed to malloc or calloc.
If we also document which of the two behaviours is used by NetBSD,
then we should be careful not to encourage callers to reply on
that implementation decision, because it may change in the future
while remaining compatible with relevant standards.
