Problem: Using feedkeys() does not work to test Insert mode completion.
(Lifepillar)
Solution: Do not check for typed keys when executing :normal or feedkeys().
Fix thesaurus completion not working when 'complete' is empty.
Problem: Slow redrawing with DirectX.
Solution: Avoid calling gui_mch_flush() unnecessarily, especially when
updating the cursor. (Ken Takata, closes#2560)
Problem: Cannot use 'balloonexpr' in a terminal.
Solution: Add 'balloonevalterm' and add code to handle mouse movements in a
terminal. Initial implementation for Unix with GUI.
Problem: Mac features are confusing.
Solution: Make feature names more consistent, add "osxdarwin". Rename
feature flags, cleanup Mac code. (Kazunobu Kuriyama, closes#2178)
Problem: FEAT_WINDOWS adds a lot of #ifdefs while it is nearly always
enabled and only adds 7% to the binary size of the tiny build.
Solution: Graduate FEAT_WINDOWS.
Problem: Bogus characters appear when indenting kicks in while doing a
visual-block append.
Solution: Recompute when indenting is done. (Christian Brabandt)
Problem: In Insert mode, CTRL-N at start of the buffer does not work
correctly. (zuloloxi)
Solution: Wrap around the start of the buffer. (Christian Brabandt)
Problem: When 'hlsearch' is set and matching with the last search pattern
is very slow, Vim becomes unusable. Cannot quit search by
pressing CTRL-C.
Solution: When the search times out set a flag and don't try again. Check
for timeout and CTRL-C in NFA loop that adds states.
Problem: Crash when complete() is called after complete_add() in
'completefunc'. (Lifepillar)
Solution: Bail out if compl_pattern is NULL. (closes#1668)
Also avoid using freed memory.
Problem: When the window scrolls horizontally when the popup menu is
displayed part of it may not be cleared. (Neovim issue #6184)

Problem: When using CTRL-X CTRL-U inside a comment, the use of the comment
leader may not work. (Klement)
Solution: Save and restore did_ai. (Christian Brabandt, closes#1494)
Problem: When using complete() and typing a character undo is saved after
the character was inserted. (Shougo)
Solution: Save for undo before inserting the character.
Problem: Insert mode completion does not respect "start" in 'backspace'.
Solution: Check whether backspace can go before where insert started.
(Hirohito Higashi)
Problem: Under some circumstances, one needs to type Ctrl-N or Ctrl-P twice
to have a menu entry selected. (Lifepillar)
Solution: call ins_compl_free(). (Christian Brabandt, closes#1411)
Problem: Pasting in Insert mode does not work when bracketed paste is used
and 'esckeys' is off.
Solution: When 'esckeys' is off disable bracketed paste in Insert mode.
Problem: When using bracketed paste line breaks are not respected.
Solution: Turn CR characters into a line break if the text is being
inserted. (closes#1404)
Problem: Internally used commands for CTRL-Z and mouse click end up in
history. (Matthew Malcomson)
Solution: Use do_cmdline_cmd() instead of stuffing them in the readahead
buffer. (James McCoy, closes#1395)
Problem: Cancelling completion still inserts text when formatting is done
for 'textwidth'. (lacygoill)
Solution: Don't format when CTRL-E was typed. (Hirohito Higashi,
closes#1312)
Problem: Cannot make Vim fail on an internal error.
Solution: Add IEMSG() and IEMSG2(). (Domenique Pelle) Avoid reporting an
internal error without mentioning where.
Problem: When using Insert mode completion with 'completeopt' containing
"noinsert" with CTRL-N the change is not saved for undo. (Tommy
Allen)
Solution: Call stop_arrow() before inserting for any key.
