The output redirection didn't work as stderr was redirected to /dev/null, as was stdout. This appears to be not what was intended so the order of redirections is fixed so that stderr is redirected to stdout instead.

Very long lines, lacks sign-off.

I think this very much is done deliberately by somebody who knows the
shell to discard everything.

And if it is beneficial to show the error, you just do not touch fd #2,
like this:

	git checkout "$onto^0" >/dev/null

As I do not see any reason to send the error message to stdout like you
did.

I also suspect that this part of the script predates 6124aee (add a quiet
option to git-checkout, 2007-02-01) where the command learned to be more
quiet during the normal operation.  Perhaps you can replace the line with

	git checkout -q "$onto^0"

and be done with it.  I haven't tested it, though.
