A shell's prompt drawn on the alternate screen is a prompt: a terminal whose program was killed there is no longer busy for ever
htop killed with `sig KILL` leaves the emulator on its alternate screen;
bash comes back and draws its prompt there, marks and all, but
promptInputReady refused any prompt on the alternate screen, so
pty/status said busy 1 and pty/run answered a bare `busy` for good.
A prompt mark there now counts. A run sent at such a prompt leaves the
alternate screen in the emulator first, as a reused command pane does,
so its output lands on the primary screen and is read whole, not
`exit 0 cut` with nothing. Busy there with no prompt drawn, and no
program name to give, a run is told `busy alternate screen`.
