    Update Texi2html/common.css default design model to remove colon after
    dl dt definition. If they are present, it is hard to use list without
    them. Otherwise, if we remove them we can use dl dt definitions with
    and without colons. So remove it from css definitions. If you want to
    use colons after dl dt say so inside html definition when building the
    list.
