Problem: Using a function pointer instead of the actual function, which we
know.
Solution: Change mb_ functions to utf_ functions when already checked for
Unicode. (Dominique Pelle, closes#1582)
Problem: Storing a zero byte from a multi-byte character causes fold text
to show up wrong.
Solution: Avoid putting zero in ScreenLines. (Christian Brabandt,
closes#1567)
Problem: Tabs are not aligned when scrolling horizontally and a Tab doesn't
fit. (Axel Bender)
Solution: Handle a Tab as a not fitting character. (Christian Brabandt)
Also fix that ":redraw" does not scroll horizontally to show the
cursor. And fix the test that depended on the old behavior.
Problem: With 'linebreak' set and 'breakat' includes ">" a double-wide
character results in "<<" displayed.
Solution: Check for the character not to be replaced. (Ozaki Kiichi,
closes#1456)
Problem: If [RO] in the status line is translated to a longer string, it is
trunctted to 4 bytes.
Solution: Skip over the resulting string. (Jente Hidskes, closes#1499)
Problem: If a wide character doesn't fit at the end of the screen line, and
the line doesn't fit on the screen, then the cursor position may
be wrong. (anliting)
Solution: Don't skip over wide character. (Christian Brabandt, closes#1408)
Problem: When concealing is active and the screen is resized in the GUI it
is not immediately redrawn.
Solution: Use update_prepare() and update_finish() from
update_single_line().
Problem: When update_single_line() is called recursively, or another screen
update happens while it is busy, errors may occur.
Solution: Check and update updating_screen. (Christian Brabandt)
Problem: Using a NULL pointer when using feedkeys() to trigger drawing a
tabline.
Solution: Skip drawing a tabline if TabPageIdxs is NULL. (Dominique Pelle)
Also fix recursing into getcmdline() from the cmd window.
Problem: Display problem with 'foldcolumn' and a wide character.
(esiegerman)
Solution: Don't use "extra" but an allocated buffer. (Christian Brabandt,
closes#1310)
Problem: Test_help_complete sometimes fails in MS-Windows console.
Solution: Use getcompletion() instead of feedkeys() and command line
completion. (Hirohito Higashi)
Problem: When a match ends in part of concealed text highlighting, it might
mess up concealing by resetting prev_syntax_id.
Solution: Do not reset prev_syntax_id and add a test to verify. (Christian
Brabandt, closes#1092)
Problem: In the GUI when redrawing the cursor it may be on the second half
of a double byte character.
Solution: Correct the cursor column. (Yasuhiro Matsumoto)
Problem: Using 'hlsearch' highlighting instead of matchpos if there is no
search match.
Solution: Pass NULL as last item to next_search_hl() when searching for
'hlsearch' match. (Shane Harper, closes#1013)
Problem: Warning for assigning negative value to unsigned. (Danek Duvall)
Solution: Make cterm_normal_fg_gui_color and _bg_ guicolor_T, cast to long_u
only when an unsigned is needed.
Problem: When using matchaddpos() a character after the end of the line can
be highlighted.
Solution: Only highlight existing characters. (Hirohito Higashi)
Problem: In the GUI the cursor is hidden when redrawing any window,
causing flicker.
Solution: Only undraw the cursor when updating the window it's in.
Problem: Setting 'display' to "lastline" is a drastic change, while
omitting it results in lots of "@" lines.
Solution: Add "truncate" to show "@@@" for a truncated line.
Problem: The cursor blinking stops or is irregular when receiving date over
a channel and writing it in a buffer, and when updating the status
line. (Ramel Eshed)
Solution: Make it a bit better by flushing GUI output. Don't redraw the
cursor after updating the screen if the blink state is off.
Problem: Still cursor flickering when a callback updates the screen. (David
Samvelyan)
Solution: Put the cursor in the right position after updating the screen.
Problem: GUI: cursor drawn in wrong place if a timer callback causes a
screen update. (David Samvelyan)
Solution: Also redraw the cursor when it's blinking and on.
Problem: syn-cchar defined with matchadd() does not appear if there are no
other syntax definitions which matches buffer text.
Solution: Check for startcol. (Ozaki Kiichi, haya14busa, closes#757)
Problem: When using try/catch in 'tabline' it is still considered an
error and the tabline will be disabled.
Solution: Check did_emsg instead of called_emsg. (haya14busa, closes#746)
