It's a bit more complicated than that, but I see your point. I
initially looked at the output and saw "something" and moved on. I
should have examined the json output more carefully.

This is because I changed the function signature, I think. Both IEOT
and EOIE extensions, if I'm not mistaken, are never tested in the test
suite. You need to set GIT_TEST_INDEX_THREADS, then the last three
