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.
