patch 9.0.2134: ml_get error when scrolling Commit: https://github.com/vim/vim/commit/c4ffeddfe5bd1824650e9b911ed9245bf56c69e3 Author: Christian Brabandt <cb@256bit.org> Date: Mon Nov 27 23:25:03 2023 +0100 patch 9.0.2134: ml_get error when scrolling Problem: ml_get error when scrolling after delete Solution: mark topline to be validated in main_loop if it is larger than current buffers line count reset_lnums() is called after e.g. TextChanged autocommands and it may accidentally cause curwin->w_topline to become invalid, e.g. if the autocommand has deleted some lines. So verify that curwin->w_topline points to a valid line and if not, mark the window to have w_topline recalculated in main_loop() in update_topline() after reset_lnums() returns. fixes: #13568 fixes: #13578 Signed-off-by: Christian Brabandt <cb@256bit.org>
