* This routine indicates to curses that a screen line is garbaged and
* should be thrown away before having anything written over the top of it.
* It could be used for programs such as editors which want a command to
* redraw just a single line. Such a command could be used in cases where
* there is a noisy line and redrawing the entire screen would be subject
* to even more noise. Just redrawing the single line gives some semblance
* of hope that it would show up unblemished.
