Usage: SET DISPLAY_ANSI [ON|OFF|TOGGLE]
  If set to on, it will allow you to display ANSI sequences unmodified
  by the client.  If set to off, ANSI sequences will be modified by
  the client to avoid corruption of your screen.

  Of all ANSI characters below 32, only the ESCAPE character is permitted
  to be displayed, all else are reverse (as ESC is if DISPLAY_ANSI is
  set to off).

  **** WARNING ****
  If you leave this set to on, you can run the risk of someone sending
  you a "keybomb" -- it is recommended you always leave this set OFF
  unless you are actually using it.
