patch 9.1.0171: Small split-move related improvements Commit: https://github.com/vim/vim/commit/5cac1a9bee0798d70a7fd80363a1f697759638e8 Author: Sean Dewar <6256228+seandewar@users.noreply.github.com> Date: Tue Mar 12 21:11:39 2024 +0100 patch 9.1.0171: Small split-move related improvements Problem: small improvements can be made to split-move related functions. Solution: apply them (Sean Dewar): - Improve some doc comments (frame_flatten should still work for non-current tabpages, despite the topframe check, which looks benign, though I'm unsure if it's still needed; see #2467). - f_win_splitmove should check_split_disallowed on wp, not targetwin, as that's what win_splitmove checks (though it's probably unnecessary to check b_locked_split at all; see #14109, which I hope to get around to finishing at some point). - Make winframe_restore restore window positions for the altframe, which winframe_remove changes. This doesn't affect the prior behaviour, as we called win_comp_pos after, but as win_comp_pos only works for curtab, and winframe_remove supports non-current tabpages, we should undo it. Regardless, this should mean we don't need win_comp_pos anymore; adjust tests to check that window positions remain unchanged. I'm not sure win_comp_pos is needed after last_status anyway if it doesn't steal rows from another frame to make room for a new statusline, which shouldn't be the case after winframe_remove? To be safe, I'll leave it as is. closes: #14185 Signed-off-by: Sean Dewar <6256228+seandewar@users.noreply.github.com> Signed-off-by: Christian Brabandt <cb@256bit.org>
