That might be useful, but I think the most useful bit of information is
whether anything at all was added (or whether the calling function
should behave as if anything at all was added, which may be a different
thing).

So even if a last_nmatches key were added to compstate, I'd still be in
favor of a useful return value from compgen et al.
