For what it's worth this is still broken, but more importantly (I'm not
just keeping bumping the same thing) the only thing that's now broken
under fsmonitor. I.e. my skip config is now GIT_SKIP_TESTS="t3404.7"
whereas before 43f1180814 ("git-mv: allow submodules and fsmonitor to
work together", 2018-09-10) I needed to add "t7411.3 t7411.4" to that.
