commit 9ccba10ebdee99c23e3f24489856dd4f01bf7a18

    Refactor tar(1) manpage
    and mark it as finished in the README.
    Specifically, add a small section on the compression flags, which
    are basically an infected GNU limb which should be removed from
    the face of the earth as soon as possible.
