Quick comments:

1. My patch could make use of completing-read-multiple.  Currently it
   uses completing-read.  So one has to do multiple "C-u x"s.

2. Magnus' changes assumes that states are just elisp symbols.  This may
   not be true.  In case of locked states - designated as USER in
   `vc-state' - the state could actually be a string.
