I think only functions that pass filenames to external programs (that
don't know about Emacs filename handlers) should unquote. Unquoting
can change the meaning of a filename.
From what I can see, project--vs-list-files shouldn't unquote, because
it doesn't pass filenames to external programs.

Yes, both of these can return quoted names.
