However, the Emacs manual still says it's possible:

  When you give a prefix argument to `vc-next-action' (`C-u C-x v v'), it
  still performs the next logical version control operation, but accepts
  additional arguments to specify precisely how to do the operation.

     * You can specify the name of a version control system.  This is
       useful if the fileset can be managed by more than one version
       control system, and Emacs fails to detect the correct one.

     * Otherwise, if using CVS or RCS, you can specify a revision ID.

       If the fileset is modified (or locked), this makes Emacs commit
       with that revision ID.  You can create a new branch by supplying an
       appropriate revision ID (*note Branches::).
