It could probably live as a separate bitfield, or an int. What scares me is "flags" sometimes is backed up then restored, but it's probably ok. But we need to extend this "flags" eventually, don't we? I don't think people will stop adding new DIFF_OPT_ flags. -- Duy -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
