Re: [PATCH v9 4/4] cat-file: add --batch-command mode

This is looking good. I think the only thing that is missing (and
which I should have realized earlier) is that there are no tests for
valid or invalid format arguments to --batch-command. I haven't
checked but there must be some other tests in the t1006 that we can
piggy back on to add that. I've left some stylistic comments below but
I don't fell strongly about them apart from the README comment so
please don't feel obliged to act on them, it's looking pretty good as
is.

Yes, I agree that this is mostly good.  I also agree with all the
points you raised in your review, including the stylistic ones.
