Hi,

cc'ing git@vger.kernel.org so that we hopefully get less of duplicated
work (and maybe even some more insights).

Please use $() instead of ``.

Why do you silence stderr?

Well, I don't like this much, but I'm not sure how to do better.

We use tabs for indentation.

I'd personally just cd "$cwd" || exit 1

You should add $GIT_DIR to $PATH only when it is not there already. This
way you can still override some of the git tools by stuffing your
overrides to $PATH.
