"git diff" before or after "git status" in the above sequence does notice what you did. Would dir/a be marked as uptodate in the index, if somebody preloads the index, after the above sequence? I hope not. -- 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
