mkfs.hfsplus and fsck.hfsplus both come from Apple. Do you think they
would pick up a patch? I'm not sure how to reach them.
I could also just patch these tools for myself. When somebody calls
_scratch_mkfs_sized() on hfsplus with an unpatched version, the test
could _notrun and tell them where to get mine. Is that acceptable?
