FWIW I think "unknown" is a nice conservative way to shrug Git's
shoulders.
When we call `git status --porcelain=v2` and read "unknown", we could
always try to find out more using additional low-level tools and/or disk
access: this is such a rare case that it does not *really* matter all that
much.
