In bug#33950 we are creating a vc command for this, but the problem is in
Git inconsistency: it uses 3 dots for diff, and 2 dots for log.

I didn't know about FETCH_HEAD because vc-git doesn't show it in the
completion list that contains only HEAD.  Maybe FETCH_HEAD should be
added to vc-git-revision-table as well?

What other useful ref names are provided by git?
