That's the direction I have thought also. But in `vc-state' there is the
following comment:
;; Note: in Emacs 22 and older, return of nil meant the file was
;; unregistered. This is potentially a source of
;; backward-compatibility bugs.
Since I don't know why nil has been replaced by `unregistered', it might
be a problem to use nil again as indication of unregistered files. And
we shouldn't change the interface wantonly, I believe.
Best regards, Michael.
