VE: Improve I and F buffer typing 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). 2020-06-09 11:23:23 +10:00			`C< DUP 0xd = IF 2DROP EXIT THEN SWAP DUP _zbuf ( c a )`

editor: add edit buffer Also, add word "C!+" and fix PSP leak in FILL. 2020-05-02 03:17:40 +10:00			`( user-facing lines are 1-based )`
