   *
   * For riched32, the rules for breaking lines seem to be the following:
   * - \r\n is one line break. This is the normal case.
   * - \r{0,2}\n is one line break. In particular, \n by itself is a line break.
   * - \r{0,N-1}\r\r\n is N line breaks.
   * - \n{1,N} are that many line breaks.
   * - \r with text or other characters (except \n) past it, is a line break. That
   *   is, a run of \r{N} without a terminating \n is considered N line breaks
   * - \r at the end of the text is NOT a line break. This differs from riched20,
   *   where \r at the end of the text is a proper line break.
