It's kind of both. 'git show HEAD' is the format that I'd personally 
expect: some meta info, including the commit message, followed by the 
diff contents.

It *can* do that. And we also have a command that shows the revision log 
message and stuff: vc-annotate-show-log-revision-at-line. We could reuse 
its logic.

And either add a diff output at the botton (making it a different 
command an dealing with major mode having to support both the headers 
and the diff), or rely on log-view-mode's bindings (the user can press 
'd' or 'D' there).
