Hmm, looks like poly_recv has the same mistake.
Ideally I think it'd be a good idea if these types did allow zero
elements, but that would clearly be a feature extension more than a bug
fix, since the implications aren't entirely obvious. I concur with
disallowing the case for existing branches. Will go apply.
