patch 9.1.0083: Redrawing can be improved when deleting lines with 'number' Commit: https://github.com/vim/vim/commit/ae07ebc04b0726e12b1af39d52e01d86ae79ef0a Author: zeertzjq <zeertzjq@outlook.com> Date: Thu Feb 8 11:37:40 2024 +0100 patch 9.1.0083: Redrawing can be improved when deleting lines with 'number' Problem: Redrawing can be improved when inserting/deleting lines with 'number'. Solution: Only redraw the number column of lines below changed lines. Add a test as this wasn't previously tested.
