Perhaps the workaround should be mentioned in the docs for xterm-mouse-mode?

That's clearly wrong, thanks for spotting it. There were problems with side-by-side windows as well. In addition, the mouse tracking was sometimes one cell off.

Please try the attached patch.

I couldn't make up my mind whether to have the mouse track the cursor or the rectangle corner. Tracking the cursor mirrors the behaviour of plain (linear) text selection, but corner tracking works better up to the right margin.

You can set mouse--rectangle-track-cursor to select either behaviour; I'm not sure if it should be a defcustom, or what the default should be. Right now it's nil (tracks the corner).
