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)
Problem: The command line takes up space even when not used.
Solution: Allow for 'cmdheight' to be set to zero. (Shougo Matsushita,
closes#10675, closes#940)
Problem: When switching window in autocmd the restored cursor position may
be wrong.
Solution: Do not restore the cursor if it was not set. (closes#10775)
Problem: Accessing freed memory after WinScrolled autocmd event.
Solution: Check the window pointer is still valid. (closes#10156)
Remove the argument from may_trigger_winscrolled().
Problem: Buffer remains active if a WinClosed event throws an exception
when there are multiple tabpages.
Solution: Ignore aborting() when closing the buffer. (closes#10101)
Problem: Memory allocation failures for new tab page not tested.
Solution: Add tests with failing memory allocation. (Yegappan Lakshmanan,
closes#10067)
