Thanks.

Do these need to be "Branch[12]", not "branch[12]" for the code to
exhibit the bug?  If not, please don't be creative in names like
these.  On case corrupting filesystems you may write Branch1 and
they may come back as branch1, but that is not what we are testing
here.

Also, style: redirection sticks to the target file, e.g.

	echo foo >>one &&

What are these blank line outputs?

All in all, I have to wonder if you can limit the updates to other
unrelated tests if you added a new test near the end.  Also doesn't
the existing test already create enough refs to let you sort with
multiple keys and demonstrate the breakage already, without adding
new refs and objects?
