A straightforward caching approach (like `completion-table-with-cache')
won't be good enough, though: the completion styles that come later tend
to query with shorter prefixes.
So all in all, it seems like the caching function has to return
completions for an empty prefix, and then cache that. That might be
pretty costly at times.
