screen: Autonuke

 
 16.6 Autonuke
 =============
 
  -- Command: autonuke STATE
      (none)
      Sets whether a clear screen sequence should nuke all the output
      that has not been written to the terminal.  SeeObuflimit.
      This property is set per display, not per window.
 
  -- Command: defautonuke STATE
      (none)
      Same as the 'autonuke' command except that the default setting for
      new displays is also changed.  Initial setting is 'off'.  Note that
      you can use the special 'AN' terminal capability if you want to
      have a terminal type dependent setting.
