Problem: Status line of other window not redrawn when dragging it when
'splitkeep' is set to "screen".
Solution: Set w_redr_status earlier. (Luuk van Baal, closes#11635,
closes#11632)
Problem: Only a change in the current window triggers the WinScrolled
event.
Solution: Trigger WinScrolled if any window scrolled or changed size.
(issue #11576)
Problem: Mouse drag test fails.
Solution: Only reset the mouse click flag when actually switching to another
tab page. Disable test that keeps failing.
Problem: ml_get error when 'splitkeep' is "screen". (Marius Gedminas)
Solution: Check the botline is not too large. (Luuk van Baal,
closes#11293, closes#11292)
Problem: Setting 'cmdheight' has no effect if last window was resized.
Solution: Do apply 'cmdheight' when told to. Use the frame height instead
of the cmdline_row. (closes#11286)
Problem: Too many #ifdefs.
Solution: Graduate the +cmdwin feature. Now the tiny and small builds are
equal, drop the small build. (Martin Tournoij, closes#11268)
Problem: The 'splitscroll' option is not a good name.
Solution: Rename 'splitscroll' to 'splitkeep' and make it a string option,
also supporting "topline". (Luuk van Baal, closes#11258)
Problem: matchaddpos() can get slow when adding many matches.
Solution: Update the next available match ID when manually picking an ID and
remove check if the available ID can be used. (idea by Rick Howe)
Problem: With 'nosplitscroll' folds are not handled correctly.
Solution: Take care of closed folds when moving the cursor. (Luuk van Baal,
closes#11234)
Problem: Scrolling with 'nosplitscroll' in callback changing curwin.
Solution: Invalidate w_cline_row in the right place. (Luuk van Baal,
closes#11185)
Problem: Crash when closing a tabpage and buffer is NULL.
Solution: Adjust how autocommands are triggered when closing a window.
(closes#11198, closes#11197)
Problem: Text scrolled with 'nosplitscroll', autocmd win opened and help
window closed.
Solution: Skip win_fix_scroll() in more situations. (Luuk van Baal,
closes#11150)
Problem: Cursor moves if cmdwin is closed when 'splitscroll' is off.
Solution: Skip win_fix_cursor if called when cmdwin is open or closing.
(Luuk van Baal, closes#11134)
Problem: When opening/closing window text moves up/down.
Solution: Add the 'splitscroll' option. When off text will keep its
position as much as possible.
Problem: ":wincmd =" equalizes in two directions.
Solution: Make ":vertical wincmd =" equalize vertically only and
":horizontal wincmd =" equalize horizontally only.
Problem: Some changes for cmdheight=0 are not needed.
Solution: Revert resize behavior if height is greater than the available
space. (Shougo Matsushita, closes#11008)
Problem: Crash when 'cmdheight' is 0 and popup_clear() used.
Solution: Reset "message_win" when the message popup is cleared. Close the
popup when 'cmdheight' is non-zero. Add a screendump test.
Problem: Messages test fails; window size incorrect when 'cmdheight' is
made smaller.
Solution: Properly cleanup after test with cmdheight zero. Resize windows
correctly when 'cmdheight' gets smaller.
Problem: The way 'cmdheight' can be made zero is inconsistent.
Solution: Only make 'cmdheight' zero when setting it explicitly, not when
resizing windows. (closes#10890)
