rl_already_prompted requires that the application has printed rl_prompt,
not some random string that isn't the prompt passed to readline().
Otherwise, it has no way of knowing where the cursor is or the data
that's on the screen, which will corrupt redisplay.

It probably `worked' in readline-7.0 because readline didn't happen to
reprint the prompt when it was doing redisplay.
