A cleaner alternative may be to fix that while git-pull is still a
script, as you seem to already know what is broken and what in the
current code needs to be fixed in what way exactly.  Perhaps do that
at the earlier part of (or even as an independent patch outside)
this series and add this test to protect the fix from getting broken
later (with expect-failure flipped to expect-success)?

Thanks.
