The code that handles version backups (file.~ver~) is already in
vc-hooks.el, which is always loaded.  The code to actually use this in a
diff operation is almost trivial, and is currently in vc-diff-internal
(vc.el).

I think it would be much easier to simply duplicate this part in pcvs. 
Or else, just move vc-diff-internal into vc-hooks.el and use that from
pcvs.

But how to actually do it is Stefan's call.  I just don't think it
warrants a new .el file.
