I had made space be "next page" to comply with the seemingly standard
emacs read-only buffer metaphor of space being page down, backspace
being page up, and q being quit.  But I agree for using the fuzzy
completor for normal everyday completion this could be a really useful
feature.

While we're talking about this, would it be helpful for it to try and
"learn" your prefered completions?  i.e. if one completes "mvl" and
picks "multiple-values-limit", that would get a higher score next time.
While this would promote trying to have the right completion at the top,
it would also mean the list is always shuffling around a bit, which
could be distracting.  (I put a fuzzy-completion-selected hook in Swank
with the expectation of doing something like this, but never used it.)
