Re: master 2a81c5d 1/2: Confine vc-stay-local to CVS, because it was unusable in SVN.

This is the issue.

In vc-registered, we end up in this loop now:

      ;; There is no file name handler.
      ;; Try vc-BACKEND-registered for each handled BACKEND.
      (catch 'found
        (let ((backend (vc-file-getprop file 'vc-backend)))
          (mapc
           (lambda (b)
             (and (vc-call-backend b 'registered file)
                  (vc-file-setprop file 'vc-backend b)
                  (throw 'found t)))
           (if (or (not backend) (eq backend 'none))
               vc-handled-backends
             (cons backend vc-handled-backends))))
        ;; File is not registered.
        (vc-file-setprop file 'vc-backend 'none)
        nil)))))

where we call each backend for each VC backend.  This code used to look
like:

                 ;; vc-registered sets the vc-backend property
                 (t (if (vc-registered file-or-list)
                        (vc-file-getprop file-or-list 'vc-backend)
                      nil)))))

So the problem is just that the bzr handler bugs out when you call it on
a file that isn't covered by bzr.
