Problem: When 'list' is set Visual mode does not highlight anything in
empty lines. (mgaleski)
Solution: Check the value of lcs_eol in another place. (Christian Brabandt)
Problem: The search highlighting and match highlighting replaces the
cursorline highlighting, this doesn't look good.
Solution: Combine the highlighting. (Yasuhiro Matsumoto)
Problem: When 'compatible' is reset 'numberwidth' is set to 4, but the
effect doesn't show until a change is made.
Solution: Check if 'numberwidth' changed. (Christian Brabandt)
Problem: 'foldcolumn' may be set such that it fills the whole window, not
leaving space for text.
Solution: Reduce the foldcolumn width when there is not sufficient room.

Problem: With a wrapping line the cursor may not end up in the right place.
(Nazri Ramliy)
Solution: Adjust n_extra for a Tab that wraps. (Christian Brabandt)
Problem: The "precedes" entry in 'listchar' will be drawn when 'showbreak
is set and list is not.
Solution: Only draw this character when 'list' is on. (Christian Brabandt)
Problem: When using conceal with linebreak some text is not displayed
correctly. (Grüner Gimpel)
Solution: Check for conceal mode when using linebreak. (Christian Brabandt)
Problem: No 'cursorline' highlighting when the cursor is on a line with
diff highlighting. (Benjamin Fritz)
Solution: Combine the highlight attributes. (Christian Brabandt)
Problem: When matchaddpos() uses a length smaller than the number of bytes
in the (last) character the highlight continues until the end of
the line.
Solution: Change condition from equal to larger-or-equal.
Problem: When there are matches to highlight the whole window is redrawn,
which is slow.
Solution: Only redraw everything when lines were inserted or deleted.
Reset b_mod_xlines when needed. (Alexey Radkov)
Problem: Cannot wrap lines taking indent into account.
Solution: Add the 'breakindent' option. (many authors, final improvements by
Christian Brabandt)
Problem: Using a regexp pattern to highlight a specific position can be
slow.
Solution: Add matchaddpos() to highlight specific positions efficiently.
(Alexey Radkov)
Problem: When using double-width characters the text displayed on the
command line is sometimes truncated.
Solution: Reset the string lenght. (Nobuhiro Takasaki)
Problem: It's possible that redrawing the status lines causes
win_redr_custom() to be called recursively.
Solution: Protect against recursiveness. (Yasuhiro Matsumoto)
Problem: Setting/resetting 'lbr' in the main help file changes alignment
after a Tab. (Dimitar Dimitrov)
Solution: Also use the code for conceal mode where n_extra is computed for
'lbr'.
Problem: The first ":echo 'hello'" command output doesn't show. Mapping
for <S-F3> gets triggered during startup.
Solution: Add debugging code for the termresponse. When receiving the "Co"
entry and when setting 'ambiwidth' redraw right away if possible.
Add redraw_asap(). Don't set 'ambiwidth' if it already had the
right value. Do the 'ambiwidth' check in the second row to avoid
confusion with <S-F3>.
Problem: In diff mode 'cursorline' also draws in the non-active window.
When 'nu' and 'sbr' are set the 'sbr' string is not underlined.
Solution: Only draw the cursor line in the current window. Combine the
'cursorline' and other highlighting attributes. (Christian
Brabandt)
Problem: Matches from matchadd() might be highlighted incorrectly when they
are at a fixed position and inserting lines. (John Szakmeister)
Solution: Redraw all lines below a change if there are highlighted matches.
