line overflow markers

[Matyas]

I am using emacs 23.1 which displays two black bars on both sides of the text
area.  It is used to display markers when a line is too long and wraps around.

I keep my lines under 80 chars so this is not really useful for me and I
could really use those extra few pixels.  I could fit an emacs window and a
terminal window (or two emacs windows) next to each other without overlap
with the font selection of my choice.

Is there a way to turn off these line overflow markers and reclaim the space?
(I already turn off the scroll bars, graphical buttons.)

Thanks!
