This follows quite familiar pattern found in receive_pack_config();
looking good.

I see this used in the previous test for receive.fsck.skipList, but
it is an interesting implementation of "git update-ref" that could
be affected by potential fsck error in push-to-receive-pack transport.
As we are interested in transport into "dst" and we want this creation
of our 'bogus' branch to succeed no matter what, it probably is not
a good idea to use "git push ." like this in the context of this test.
Perhaps leave a 'leftoverbits' comment to force us remember to update
all these uses of local push from the script in the future?

We see that by default fetch.fsckObjects errors out when it notices
the bogus commit object.

And then we set up a skip to see ...

... if that is ignored. Looks great.
Would this second attempt succeed _without_ the SKIP list, I wonder,
though?
After the initial attempt that transferred the object, inspected it
and then aborted before pointing a ref to make the object reachable,
wouldn't it be possible for the quickfetch codepath to say "ah, we
locally have that object, so let's see it is a descendant of the tip
of one of our refs *and* all the objects it points at (recursively)
are all available in this repository", as we do not quarantine on
the fetch side?
