Problem: Crash when BufAdd autocommand wipes out the buffer.
Solution: Check for buffer to still be valid. Postpone freeing the buffer
structure. (Hirohito Higashi)
Problem: Crash when wiping out buffer triggers autocommand that wipes out
only other buffer.
Solution: Do not delete the last buffer, make it empty. (Hirohito Higashi)
Problem: Cannot right shift lines starting with #.
Solution: Allow the right shift when 'cino' contains #N with N > 0.
(Christian Brabandt)
Refactor parsing 'cino', store the values in the buffer.
Problem: Autocommands are triggered by setwinvar() et al. Missing BufEnter
on :tabclose. Duplicate WinEnter on :tabclose. Wrong order of
events for :tablose and :tabnew.
Solution: Fix these autocommand events. (Zyx)
Problem: Crash when using b:, w: or t: after closing the buffer, window or
tabpage.
Solution: Allocate the dictionary instead of having it part of the
buffer/window/tabpage struct. (Yukihiro Nakadaira)
Problem: On some systems case of file names is always ignored, on others
never.
Solution: Add the 'fileignorecase' option to control this at runtime.
Implies 'wildignorecase'.
Problem: The color column is not correct when entering a buffer. (Ben
Fritz)
Solution: Call check_colorcolumn() if 'textwidth' changed. (Christian
Brabandt)
Problem: It is possible to add replace builtin functions by calling
extend() on g:.
Solution: Add a flag to a dict to indicate it is a scope. Check for
existing functions. (ZyX)
Problem: When using :tablose a TabEnter autocommand is triggered too early.
(Karthick)
Solution: Don't trigger *Enter autocommands before closing the tab.
(Christian Brabandt)
Problem: When closing a window or buffer autocommands may close it too,
causing problems for where the autocommand was invoked from.
Solution: Add the w_closing and b_closing flags. When set disallow ":q" and
":close" to prevent recursive closing.
Problem: ":tab drop file" has several problems, including moving the
current window and opening a new tab for a file that already has a
window.
Solution: Refactor ":tab drop" handling. (Hirohito Higashi)
Problem: Crash when a BufWinLeave autocommand closes the only other window.
(Daniel Hunt)
Solution: Abort closing a buffer when it becomes the only one.
Problem: ":12verbose call F()" may duplicate text while trying to truncate.
(Thinca)
Solution: Only truncate when there is not enough room. Also check the byte
length of the buffer.
Problem: When closing a window there is a chance that deleting a scrollbar
triggers a GUI resize, which uses the window while it is not in a
valid state.
Solution: Set the buffer pointer to NULL to be able to detect the invalid
situation. Fix a few places that used the buffer pointer
incorrectly.
Problem: When 'colorcolumn' is set locally to a window, ":new" opens a
window with the same highlighting but 'colorcolumn' is empty.
(Tyru)
Solution: Call check_colorcolumn() after clearing and copying options.
(Christian Brabandt)
Problem: No spell highlighting when re-using an empty buffer.
Solution: Clear the spell checking info only when clearing the options for a
buffer. (James Vega)
