Now this points to another issue: 
vc-next-action does this:

      (mapc 'vc-register files))

But vc-register is defined like this:

(defun vc-register (&optional set-revision comment)

i.e. it does not have a file parameter, it works on the current
buffer.

The easy fix would probably be to change the mapc call to do a
with-current-buffer. But it might be better to change vc-register to
take a fileset parameter...
