A comment on the comment: what is an "item"?  It looks to me like the
proposed 'allparents' is an option common to many commands.  If I'm
correct, you should probably refer to it as the "--allparents option".

Also, I think the notion of "at most two parents" is pretty hardwired
in the guts of Mercurial.  So it would be equally accurate, and
possibly clearer, to make this --bothparents.
