vc-svn-after-dir-status

[Nick Roberts <nickrob@snap.net.nz>]

The regexp in vc-svn-after-dir-status is wrong for unregistered files in the
remote case as "svn status -u" doesn't output a revision number for such a
state.  This means that files in this state aren't displayed in this case.  I
think the patch below fixes it but couldn't test it as I encountered bugs which
stopped vc-dir from working.  These were in vc-dir-update in vc-dir.el, and
occurred because prev-node in (vc-dir-node-directory prev-node) was nil 
when files needed updating and expand-file-name somwhere had a nil argument
when there were no files that needed updating.

	*  (vc-svn-after-dir-status): Use shy group for revision number
        as it isn't present for unregistered files.
