Problem: Alloc() returning "char_u *" causes a lot of type casts.
Solution: Have it return "void *". (Mike Williams) Define ALLOC_ONE() to
check the simple allocations.
Problem: Using "int" for alloc() often results in compiler warnings.
Solution: Use "size_t" and remove type casts. Remove alloc_check(), Vim
only works with 32 bit ints anyway.
Problem: Hang when concealing the '>' shown for a wide char that doesn't
fit in the last cell.
Solution: Put back the pointer when the '>' is not going to be displayed.
(closes#4377)
Problem: Cannot flush change listeners without also redrawing. The line
numbers in the list of changes may become invalid.
Solution: Add listener_flush(). Invoke listeners before adding a change
that makes line numbers invalid.
Problem: No docs or tests for listener functions.
Solution: Add help and tests for listener_add() and listener_remove().
Invoke the callbacks before redrawing.
Problem: Borland support is outdated and doesn't work.
Solution: Remove Borland support, there are other (free) compilers
available. (Thomas Dziedzic, Ken Takata, closes#4364)
Problem: "extends" from 'listchars' is used when 'list' is off. (Hiroyuki
Yoshinaga)
Solution: Only use the "extends" character when 'list' is on. (Hirohito
Higashi, closes#4360)
Problem: No test for mouse clicks in the terminal tabpage line.
Solution: Add a test. (Dominique Pelle, closes#4247). Also init
TabPageIdxs[], in case it's used before a redraw.
Problem: Composing chars on space wrong when 'listchars' is set.
Solution: Do not use "space" and "nbsp" entries of 'listchars' when there is
a composing character. (Yee Cheng Chin, closes#4197)
Problem: "Conceal" match is mixed up with 'hlsearch' match.
Solution: Check that a match is found, not a 'hlsearch' item. (Andy
Massimino, closes#4073)
Problem: When 'listchars' is set a composing char on a space is wrong.
Solution: Separate handling a non-breaking space and a space. (Yasuhiro
Matsumoto, closes#4046)
Problem: Extending sign and foldcolumn below the text is confusing.
Solution: Let the sign and foldcolumn stop at the last text line, just like
the line number column. Also stop the command line window leader.
(Christian Brabandt, closes#3964)
Problem: Macros for MS-Windows are inconsistent, using "32", "3264 and
others.
Solution: Use MSWIN for all MS-Windows builds. Use FEAT_GUI_MSWIN for the
GUI build. (Hirohito Higashi, closes#3932)
Problem: Cursorline highlight is not always updated.
Solution: Set w_last_cursorline when redrawing. Fix resetting cursor flags
when using the popup menu.
Problem: Peeking and flushing output slows down execution.
Solution: Do not update the mode message when global_busy is set. Do not
flush when only peeking for a character. (Ken Takata)
Problem: Updating completions may cause the popup menu to flicker.
Solution: Avoid updating the text below the popup menu before drawing the
popup menu.
Problem: Showing two characters for tab is limited.
Solution: Allow for a third character for "tab:" in 'listchars'. (Nathaniel
Braun, Ken Takata, closes#3810)
Problem: Windows are updated for every added/deleted sign.
Solution: Do not call update_debug_sign(). Only redraw when the line with
the sign is visible. (idea from neovim #9479)
Problem: Tabline is not always redrawn when something that is used in
'tabline' changes.
Solution: Add ":redrawtabline" so that a plugin can at least cause the
redraw when needed.
