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. ⇒Obuflimit.
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.
