Final (hopefully) version of this patch attached.

I guess there are still issues with it, but we’re running out of time
to sort them for Emacs 26.2.

different from the last one, but it has some comment changes and a
change to how we handle requests to copy parts of the screen, since
they were the major issue still with ghosting cursors.
