Well, as long as you realize that that automatically means that you have
to walk the whole commit list, and you won't be able to get the
incremental output that git-log and friends normally are able to give?
But this patch should do it. With it,
git log --reverse --pretty=short ORIG_HEAD..
should do what you want.
It is _not_ possible to reverse the "gitk" view with this patch, though,
as this does _not_ reverse parenthood information.
The "--reverse" flag could possibly be renamed.
