I've glanced over it and tried it out and it looks good to me.

Thanks,

Perhaps mention that this function is only in pre Emacs 23.  I'm not sure that
I understand the current naming convention.  Some functions now use 'status':
vc-cvs-dir-status, while others still use 'state': vc-cvs-state-heuristic.

(let (result dirlist)

(let ((basename (match-string 1))
      (file (expand-file-name basename dir))
      (status (or (vc-file-getprop file 'vc-state)
                  (vc-cvs-parse-entry file t))))

No big deal.  Perhaps a bit clearer.
