VE: add I command Also, add insert and find buffers to the header, making it 3 lines high. Also, fix the "I" overshadowing word which wasn't operating on the proper RSP level. Also, fix I which didn't mark the block as dirty. 2020-06-05 12:54:27 +10:00			`: i COMPILE I ; IMMEDIATE ( save overshadowed )`
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			`: _I ( I without _pln and _type. used in VE )`

Add word TUCK 2020-05-23 04:17:38 +10:00			`TUCK - ( ilen chars-to-move )`
editor: simplify I with the use of MOVE- Also, delay the shadowing of DO..LOOP's I for as long as possible. 2020-05-07 11:10:27 +10:00			`SWAP EDPOS @ _cpos 2DUP + ( ctm ilen a a+ilen )`

editor: implement I command Also, made LIST properly handle full 64-chars lines not ending with a null or CR. Previously, such a line would be accompanied by its following line, duplicating that line's output. 2020-05-07 02:19:36 +10:00			`THEN`
