Too messy to overload the binding with long prefixes with different meanings.

> Or bind vc-dir-mark-registered to a new char indeed, e.g. 'r'.

Better to bind to the mnemonic key '* r' as in this patch.

I still don't understand why Drew insists on 100% compatibility
between Dired and VC-Dir - they already diverged:
'M' in Dired doesn't mark files like it does in VC-Dir.
