Message:

+ added two small functions... TurnOnBackLight? & TurnOffBackLight?, which turn on and off the LCD Backlight (or EVF backlight) - useful for energy saving or camouflage missions :D
also added ubasic and lua commands: set_backlight(x), whereas 0 disables Backlight and 1 enables it. mind you, after a shot the display is turned on again (probably loop set_backlight_statement(0) in script!?).
an example script can be found here: ​http://chdk.setepontos.com/index.php/topic,2744.msg27703.html#msg27703
todo: PERHAPS make it that you can disable (automatically after a given time?) LCD directly in CHDK, also on todo list: Dimming the light

thx to fudgey, ewavr & Dataghost, who made that happen \o/ (see ​https://chdk.kernreaktor.org/mantis/view.php?id=65 for links)
