I think this tells me that dir-state needs to set a new state value of
'unregistered when it sees status flag "?" (that's the Subversion and
Mercurial flag; there may be other local equivalents). That way the
backend check wouldn't need to be done on on a per-file basis.
This change could be a bit tricky. Right now a nil return from
vc-state means the file is unregistered. I don't know how deeply that
assumption is wired into the code.
