Thanks for the careful review.
I have one small question about the test below.
I'll base the reroll of my patch on top of this one so that
I'm including your new test while developing.
Junio, can you please queue this patch before my upcoming v3
patch when I reroll?
I also noticed that I forgot to "git reset --hard" after doing "git add"
in one of the tests I introduced so I'll be adjusting that as well in v3.

Should we use "test_must_fail grep ..." instead of "! grep ..." here?
