In batch mode vc related commands doesn't work as expected. In editor
mode it partially works, if we do a vc-<backend>-state before we do vc-state
it gives correct state and a 'vc-recompute-state' gives correct state in any
order.
I verified the latest Emacs CVS source and the behavior is still same. It
works fine with vc version shipped with Emacs v21.3.
