I would like to have a function to toggle the value of the truncate-lines
variable.  Unfortunatly doiung a setq or set-variable within a function
does not cause the window to be redrawn the was doing a M-x set-variable
command.  I am forced to use the following function, which redraws the
display after toggling the variable.  I don't want to wait for the entire
screen to be redrawn.  How do I force just the current window to be redrawn?

        (defun toggle-truncate-lines ()
          "Toggle the value of truncate-lines"
          (interactive)
          (setq truncate-lines (not truncate-lines))
          (redraw-display))
