Ok. I'm also using `vc-diff-internal', `vc-buffer-sync' and 
`vc-exec-after', but these seem to be less relevant to the current subject.

The above list includes `state', which you're saying won't be changed 
much. Other than that, do you mean `dir-status' and `dir-status-files' 
will be merged?

If that means that the new function will behave just like `dir-status' 
when passed a nil (or a directory) instead of a list of files, then how 
that's much better than keeping the functions separate? The downside is 
obvious, meanwhile (API breakage).
