patch 9.1.0414: Unable to leave long line with 'smoothscroll' and 'scrolloff' Commit: https://github.com/vim/vim/commit/b32055e504ebd4f6183a93b92b08d61dad61c841 Author: Luuk van Baal <luukvbaal@gmail.com> Date: Thu May 16 20:44:09 2024 +0200 patch 9.1.0414: Unable to leave long line with 'smoothscroll' and 'scrolloff' Problem: Unable to leave long line with 'smoothscroll' and 'scrolloff'. Corrupted screen near the end of a long line with 'scrolloff'. (Ernie Rael, after 9.1.0280) Solution: Only correct cursor in case scroll_cursor_bot() was not itself called to make the cursor visible. Avoid adjusting for 'scrolloff' beyond the text line height (Luuk van Baal) fixes: #14726 closes: #14783 Signed-off-by: Luuk van Baal <luukvbaal@gmail.com> Signed-off-by: Christian Brabandt <cb@256bit.org>
