mkdir: ?: Invalid argument

It looks like one of the odd characters that git's using for the test is an invalid character for HFS+, so the entire test fails. Perhaps this should be made a "soft" failure like all of the SVN tests passing despite me not having SVN installed, or should a different character be used somewhere? Git can't possibly be expected to work in a situation where the FS fails.
