> VC-Dir needs the same key prefix as is provided by Dired:

> * %             dired-mark-files-regexp
> * *             dired-mark-executables
> * /             dired-mark-directories
> * ?             dired-unmark-all-files
> * @             dired-mark-symlinks
> * s             dired-mark-subdir-files
>
> Then VC-Dir could provide, for example:
>
> * r             vc-dir-mark-registered
> * u             vc-dir-mark-unregistered
> ...
