What does "taking care of multiple levels of verbosity" mean? I
suppose you mean that commit.verbose specifies a verbosity level
(rather than being merely boolean), but that phrase is difficult to
decipher. And, since it's obvious from the patch itself that verbosity
is not a mere boolean, there isn't really a need to mention it here.
The commit message would be perfectly fine without that bit, so
perhaps just drop it.

Please help reviewers out by being a bit more verbose when describing
the changes. For instance, what bug did you fix pointed out by SZEDER?
And, "change some tests" says nothing useful. What did you change in
the tests?

Nit: It might be good to drop the blank line above this new
conditional to make it clear that it is part of the
init_config/parse_options processing (the tail of which is visible in
the context above).

Nit: For consistency, dropping the blank line above this new
conditional wouldn't hurt either.

Why is this test so utterly different than it was in v9 (even though
the title is the same), and why is it so different from other tests
below?

The fact that v9 broke a number of tests in other scripts which use
git-status (as SZEDER pointed out[1]), due to initializing 'verbose'
to -1 in builtin/commit.c, suggests that you probably ought to add
another test here to protect against that sort of breakage, as well.
Specifically, git-status should remain non-verbose when neither
commit.verbose nor --verbose is specified.
