   * There seems to be an Xaw problem with doing both wrap and scroll:
   * its supposed to automatically scroll to end when we change the insertion
   * point, but if a line is wrapped the scroll lags behind a line, and
   * stays behind on subsequent additions, until the too-long line scrolls
   * off the top.  (I tried setting the insert position to the last char,
   * instead of the start of line as below, but that didn't help.)  So we
   * split the line ourselves.  I'm just using a fixed length split; should
   * perhaps check and use width of output window (but font size?)  -dwp
   *
   * Now uses window's font size and width.  Assumes fixed-width font.  --jjm
