Looks like a bug in the `basic` completion style: it filters things that
match the glob pattern `fo*-function` yet it only highlights the prefix.

I don't think it could be trusted to always provide the needed data (and
even if it does, it would be sufficiently clunky to use that I'm not
sure we'd want to rely on it).
