Synopsis:
   set reverse_video [on|off|toggle]

Description:
   This setting controls how reversed text is displayed in the input line
   and the display window.  If it is turned on, the REVERSE key function
   (usually ^V; Control-V) will toggle reversed text on and off.  If off, it
   will strip out all REVERSEs In the displayed text, effectively disabling
   reversed text.
