Hmm... along the lines of --multiply I'd have said --outer as in outer
product.  You could then also have --inner as in inner product which
would concatenate lines from multiple files prior to processing.

I'd think something called "--nest" would be handy for situations
where one wants parallel to invoke parallel.
