patch 8.2.4614: redrawing too much when 'cursorline' is set Commit: https://github.com/vim/vim/commit/c20e46a4e3efcd408ef132872238144ea34f7ae5 Author: zeertzjq <zeertzjq@outlook.com> Date: Wed Mar 23 14:55:23 2022 +0000 patch 8.2.4614: redrawing too much when 'cursorline' is set Problem: Redrawing too much when 'cursorline' is set and jumping around. Solution: Rely on win_update() to redraw the current and previous cursor line, do not mark lines as modified. (closes #9996)
