Yes, I considered that, but I think that keeping the tests in their own
commit is reasonable.  The tests protect against a malfunction that we
did not notice when the implementation was done.  The commits reference
(and use similar subjects) to the original commit where we should have
introduced the tests.  If the tests fail, I think it will be easier and
less confusing to reach the original commit where the implementation was
done if we keep them separated, rather than combining all three commits.

I'm going to reorder the commits and change to use test_expect_failure().
This way the commit with the fix will also be linked.
