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)
Problem: When using try/catch in 'statusline' it is still considered an
error and the status line will be disabled.
Solution: Check did_emsg instead of called_emsg. (haya14busa, closes#729)
Problem: Display problems when the 'ambiwidth' and 'emoji' options are not
set properly or the terminal doesn't behave as expected.
Solution: After drawing an ambiguous width character always position the
cursor.
Problem: When using :stopinsert in a silent mapping the "INSERT" message
isn't cleared. (Coacher)
Solution: Always clear the message. (Christian Brabandt, closes#718)
Problem: The versplit feature makes the code uneccessary complicated.
Solution: Remove FEAT_VERTSPLIT, always support vertical splits when
FEAT_WINDOWS is defined.
Problem: Timer with an ":echo" command messes up display.
Solution: Redraw depending on the mode. (Hirohito Higashi) Avoid the more
prompt being used recursively.
Problem: With 'rightleft' and concealing the cursor may move to the wrong
position.
Solution: Compute the column differently when 'rightleft' is set. (Hirohito
Higashi)
Problem: When using 'colorcolumn' and there is a sign with a fullwidth
character the highlighting is wrong. (Andrew Stewart)
Solution: Only increment vcol when in the right state. (Christian Brabandt)
Problem: User may yank or put using the register being recorded in.
Solution: Add the recording register in the message. (Christian Brabandt,
closes#470)
Problem: Crash when using more lines for the command line than
'maxcombine'.
Solution: Use the correct array index. Also, do not try redrawing when
exiting. And use screen_Columns instead of Columns.
