This teaches "git rebase [--onto O] A B" to omit an unnecessary checkout
of branch B before it goes on.

This works for a frequent use-case of mine:

"Works" meaning "does not break", or "gives a great performance
improvement that it is worth having it early in a tagged release"?

  $ git rebase master devel

where I am already on branch master, and now want to rebase devel on top
of it.

The code seems to take care of a lot of corner cases and less frequent
use-cases, including using --onto, which I don't feel able to judge about.

+# git reset --hard "$onto^0"

Don't forget to remove this line. ;)
