    Remove any superflous non rst/html from tarball.
    
    When we in the future introduce something new and shiny here, don't
    automatically start putting it into the tarball release.
    
    This may seem a bit backward, the main idea is to avoid hardcoding
    the section/subdirectory names yet another place.
