        In the beginning this always called touchwin(). However, a bug
        was discovered in tmux when TERM was set to `xterm-256color`, where
        only part of the screen got redrawn when scrolling. tmux automatically
        sets TERM to `screen-256color`, but many people choose to override
        this in their tmux.conf or .bashrc file which can cause issues.
        Using clearok() instead seems to fix the problem, with the trade off
        of slightly more expensive screen refreshes.

        Update: It was discovered that using clearok() introduced a
        separate bug for urxvt users in which their screen flashed when
        scrolling. Heuristics were added to make it work with as many
        configurations as possible. It's still not perfect
        (e.g. urxvt + xterm-256color) will screen flash, but it should
        work in all cases if the user sets their TERM correctly.
