The main use is not when the rectangle is completely empty (i.e. when
mark = point) but when the rectangle has 0 width, so you see where the
mark is and you see on each line the 0-width boundary of the rectangle.

So changing the cursor doesn't quite give me what I want.

Hmm... that's a possibility.  Sounds costly (compared to "draw a line"),
but maybe it could work.
