A very nice simplification (but please use tabs to indent).

While at it, you could lose the space after the redirector that we seem to
no longer prefer:

> +echo $@ >.git/post-checkout.args

And since we are already cleaning up, we could easily move use
write_script instead, *and* move it into the `setup` test case (which
makes it easier to use something like

	sh t5403-post-checkout-hook.sh --run=1,13

The rest looks good (modulo indentation issues). I would have preferred
the separate concerns to be addressed in individual commits (one commit to
replace the `awk` calls, one to avoid the clones, one to simplify by using
`test_commit`, etc), as that would have been easier to review. But others
might disagree (Junio recently made the case of smooshing separate
concerns into single commits, even squashing two of my patches into one
against my wish), so... I guess you don't have to change this.

Thank you,
Johannes
