Of course, project-find-file could wrap the backend's completion table
so as to add its own `category' info to the meatadata, but
it's cumbersome.

We should try and unify the metadata returned by the completion-tables
and the metadata returned by the completion-at-point-functions (or
provided via completion-extra-properties).

Ah, I see.  But that means all the files are returned as one flat list
(without using completion-boundaries).  Might be a good idea.

Couldn't find that 25th hour!

Agreed, but occasionally I need such things, and that's where the *
globs come in handy ;-)
