Daniel Covington	6e6c16aa23	vim: paint and edit in machine code, redraw only changed rows The single-row painter became vml.s at $C000: one sys() paints all 24 rows, memmove and line-index fix-ups run in ML, and the keyboard buffer is popped with IRQs masked. dall() repaints only the cursor row or the whole screen, so j went from 17 to 0-3 jiffies. Loading now checks the drive error channel and splits lines over 80 columns. The temporary jiffy counters used to measure the speedup are removed; the numbers are in NOTES.md.

Daniel Covington	1f6fcfee17	vim: fix sys() for C64 (no bank arg), exit via KERNAL reset Power C on the C64 calls ML as sys(addr, &a, &x, &y); the bank argument from the manual's C128 library page made sys() jump to $000F and crash. The ML row painter now runs. Quitting resets through $FCE2 because Power C owns BASIC's zero-page pointers. Notes and Power C skill updated.
