My test suite is testing multiline prompts which also have PS1 and this works, up until I do not try to use prompt with empty last line. A check shows that `$options[singlelinezle]` evaluates to `off` while this problem is in effect.

Though making $LINES actually be 3 (in pexpect I used 1x300 screen, 2x300 neither did work well) fixes this bug and previously ignored bug with RPS1 not showing up was also fixed, thanks.
