Previously, it would keep the old buffer displayed why typing over it. I had kept it thus because I didn't want to erase the buffer right away because the behavior is that when we type nothing, we keep the buffer as-is and repeat the action. Now, the behavior of I and F is much better. It keeps the buffer displayed until the first non-return keystroke and then erases it. Also, fixed PSP leak in _type and fixed PSP overuse in successful _F (they balanced out).
