Ah, okay. Btw, region-history-mode is a Git-only feature, so I don't
think I understand why it is in vc.el and not in vc-git.el.

I'd prefer this to be a variant of vc-diff, and bound to "C-x v =".
The "C-u C-x v =" form is already taken, and tweaking it to accept a
single revision would not be easy. So how about "C-u C-u C-x v ="?
The reason I think this should be a vc-diff subcommand is that most
kinds of VCS describe a revision as diffs. Where a revision's
description is expected to include meta-data, i.e. the VCS backend
provides a command to show a revision in that format, we should use
that backend command, of course. But conceptually we just show diffs,
so inventing a whole new class of VC commands for a minor variant of
diffs display sounds sub-optimal to me.
Also, why only implement this for a single backend? The corresponding
diff commands exist in every VCS we support, so let's implement this
for all of them, okay? Let us know if you need help with other VCSes.
Finally, this needs documentation in NEWS and in the user manual.
