We do not have any "! git anything" in that script, don't we?  We do
not expect "grep" supplied by the platform to lie, and that is why
we should never use test_must_fail on them, but we do want to notice
when git starts segfaulting, and that is what test_must_fail is for.

We tell novices and cluelesses who do not know better to try to
follow and match the surrounding style.  This is because it would at
least not make things worse than if we let them run loose on our
codebase.  It is not about "if we have a bad style, it is better to
match that existing bad style to spread the badness than making it
partly better".  But you have been here long enough and know what is
preferred and and what is to be avoided---more importantly, Peff has
been here long enough to know and has given such an advice, so...

In any case, I do not offhand see anything wrong style-wise in 7510,
so please do not change anything in it for the sake of styles.
