For the moment, I'm happy to leave things as they are, and I'll
interpret version 1 of the hash version field as whatever hash is in use
elsewhere in .git.  If you're going to bump the version in the future,
feel free to CC me on the patches, and we'll make sure that we serialize
the format_version field in the file then.
