Here I also doubt it's worth the trouble: the "multiple arg" version of
those predicates was only added recently so it's not used very often,
and of those cases I doubt many of them would benefit from
your optimization.

So I installed a simpler patch which just fixes the bogus optimization
when there are more than 2 args.
