patch 9.1.0100: Redrawing can be improved with undo and 'spell' Commit: https://github.com/vim/vim/commit/f2d90a351159fd6843f450850f52004f42e00183 Author: zeertzjq <zeertzjq@outlook.com> Date: Mon Feb 12 20:28:01 2024 +0100 patch 9.1.0100: Redrawing can be improved with undo and 'spell' Problem: When undoing with 'spell', redrawWinline() is called after changed_lines(), while later win_update() sets redraw type to UPD_NOT_VALID, even though w_redraw_top and w_redraw_bot are still valid. Solution: Only set redraw type to UPD_NOT_VALID when inserting/deleting lines after parts of window has pending redraw, i.e., when changed_lines() is called after redrawWinline().
