patch 9.1.0215: Half-page scrolling does not support smooth-scrolling Commit: https://github.com/vim/vim/commit/5a2e3ec9ac72b6e644fea4ebba7e632498296e2f Author: Luuk van Baal <luukvbaal@gmail.com> Date: Thu Mar 28 10:07:29 2024 +0100 patch 9.1.0215: Half-page scrolling does not support smooth-scrolling Problem: Page-wise scrolling with Ctrl-D/Ctrl-U implements it's own logic to change the topline and cursor. More logic than necessary for scrolling with Ctrl-F/Ctrl-B was removed in patch 9.1.0211. Solution: Re-use the logic from Ctrl-E/Ctrl-Y/Ctrl-F/Ctrl-B while staying backward compatible as much as possible. Restore some of the logic that determined how many lines will be scrolled (Luuk van Baal) closes: #14316 Signed-off-by: Luuk van Baal <luukvbaal@gmail.com> Signed-off-by: Christian Brabandt <cb@256bit.org>
