There are two ways of doing this I can think of.  The standard technique
is to XOR the lines you want onto the screen;  when you want rid of
them, XOR them again.  You should be warned that this patented, despite
being fairly damn obvious:  I independently re-invented it when I was
12.  The only alternative I can think of is to redraw the stuff behind
the cursor when you remove them, or to draw the cursor as two windows
arranged in a cross shape in the hope that backing store will do its
stuff.  Backing store is _also_ patented, in the US at least.

I didn't mean to do this, but since I'm here I shall: if you think this
is a little silly, talk to the League for Programming Freedom:
