That's fine.  We are not in a hurry.

I do not think we would want to see "FIXED" on systems that
already behave sanely, so we would want a fix-up like this on
top of your patch, and it would be a good to go.

I do not have a handy way to test this, though, so can you try
it out and make sure test_case and test_unicode are set to
test_expect_failure correctly on problematic filesystems?

Thanks.
