Done!

I tried adapting it, but my test failed, because I had failed to adapt
one of the users.  I find that using #f to denote the absence of a
prefix more accurate than "" (after all, "" is a valid prefix) and
composes better (should we want to 'or' a couple of prefix seeking
procedures together).
