That can be read from the patch.  Also the subject tells us a half
of what you want to achieve with this change (by the way, your
subject is malformatted and lacks the <area>: prefix; perhaps
"[PATCH] tests: make commit object names reproducible" or something),
but the readers are left hanging without knowing what motivated the
change.  Do any test pieces in these scripts change their behaviour
based on what exact object names are assigned to them, making them
flaky and hard to test, and if so which one and in what way?

Thanks.
