Ah, this looks vaguely familiar. Thanks for resurrecting the topic.
The clearing is merely to avoid leaks, and the primary change to the
function is to immediately return 0.

Here, before reporting the push result, when we are doing ATOMIC,
we tweak the result we are going to report to atomic-push-failed.

This roughly corresponds to what send-pack.c::atomic_push_failure()
does. Here, we avoid overwriting a status that already signals a
failure. The list of "good" statuses used here match what is used
at the end of send_pack.c::send_pack(), which decides the final
outcome of "git push" for the native transport.
Looks good.
By the way, I rearranged the patch as I happen to agree with Dscho
that the additional {} was unwarranted and made it harder to review.
It is clear that we need to tweak the status before reporting.
