While this would be easier on _my_ fingers as well, I have a
suspicion that it might make more sense to make this "single
ref" case to mean "HEAD~5^..HEAD~5" (if we _were_ designing a
new command that is called format-patch today, that would be
more natural).  But probably it is too late to break it by now.

I'd rather not expose such revision.c internals too much.  An
alternative approach would be to give instruction to revision.c
(read: another flag like rev.no_walk) to tell it to do something
special when the user has only one commit, but I think what you
did in your patch is cleaner and sufficient.

Also we probably would want to default the diff options to show
the root commit diff (rev.show_root_diff).
