Great catch and thank you for the test case! It seems that when I applied the patch, it misapplied, but not in a way that caused a test failure. I have no idea how that happened, but I assume I screwed up something with git somewhere along the way and caused the failure.

I've pushed baa2b8d08502acfa91a8dfd699d25f7b4e25edbb to fix it. Thanks!
