patch 9.1.0118: Use different restoration strategy in win_splitmove Commit: https://github.com/vim/vim/commit/704966c2545897dfcf426dd9ef946aeb6fa80c38 Author: Sean Dewar <6256228+seandewar@users.noreply.github.com> Date: Tue Feb 20 22:00:33 2024 +0100 patch 9.1.0118: Use different restoration strategy in win_splitmove Problem: saving and restoring all frames to split-move is overkill now that WinNewPre is not fired when split-moving. Solution: defer the flattening of frames until win_split_ins begins reorganising them, and attempt to restore the layout by undoing our changes. (Sean Dewar) This also means we no longer must allocate. related: #14042 Signed-off-by: Sean Dewar <6256228+seandewar@users.noreply.github.com> Signed-off-by: Christian Brabandt <cb@256bit.org>
