For the changed files relative to HEAD, you can call the backend command 
(with vc-call-backend) named dir-status-files. But there is no way to 
specify the reference revision. Maybe calling the VC backend diff 
command on the whole repo and parsing the output could work.

I'll need some more details to answer this.
