Stop repainting after paste

"repaint" here is a bit of a misnomer. It *doesn't* re-highlight, that
just happens on its own.

It re-runs the prompt, which can take quite a while (depending on the
configuration), and which is also useless in this context as this
isn't something the prompt will be reacting to (theoretically it
could, but I doubt the utility of displaying "PASTE" for a few milliseconds).
