Problem: Deleting signs and completion for :sign is insufficient.
Solution: Add deleting signs in a specified or any group from the current
cursor location. Add group and priority to sign command
completion. Add tests for different sign unplace commands. Update
help text. Add tests for sign jump with group. Update help for
sign jump. (Yegappan Lakshmanan, closes#3731)
Problem: Using sign group names is inefficient.
Solution: Store group names in a hash table and use a reference to them.
Also remove unnecessary use of ":exe" from the tests. (Yegappan
Lakshmanan, closes#3715)
Problem: Placing signs can be complicated.
Solution: Add functions for defining and placing signs. Introduce a group
name to avoid different plugins using the same signs. (Yegappan
Lakshmanan, closes#3652)
Problem: When executing an insecure function the secure flag is stuck.
(Gabriel Barta)
Solution: Restore "secure" instead of decrementing it. (closes#3705)
Problem: Cannot build without the sandbox.
Solution: Set the secure option instead of using the sandbox. Also restrict
the characters from 'spelllang' that are used for LANG.vim.
(suggested by Yasuhiro Matsumoto)
Problem: Pointer ownership around fname_expand() is unclear.
Solution: Allow b_ffname and b_sfname to point to the same allocated memory,
only free one. Update comments.
Problem: Cannot get the script line number when executing a function.
Solution: Store the line number besides the script ID. (Ozaki Kiichi,
closes#3362) Also display the line number with ":verbose set".
Problem: Crash when a callback deletes a window that is being used.
Solution: Do not unload a buffer that is being displayed while redrawing the
screen. Also avoid invoking callbacks while redrawing.
(closes#2107)
Problem: File info message not always suppressed with 'F' in 'shortmess'.
(Asheq Imran)
Solution: Save and restore msg_silent. (Christian Brabandt, closes#3221)
Problem: Not restoring Insert mode if leaving a prompt buffer by using a
mouse click.
Solution: Set b_prompt_insert appropriately. Also correct cursor position
when moving cursor to last line.
Problem: Buffer-local window options may not be recent if the buffer is
still open in another window.
Solution: Copy the options from the window instead of the outdated window
options. (Bjorn Linse, closes#2336)
Problem: :argedit does not reuse an empty unnamed buffer.
Solution: Add the BLN_CURBUF flag and fix all the side effects. (Christian
Brabandt, closes#2713)
Problem: A TextChanged autocmd triggers when it is defined after creating a
buffer.
Solution: Set b_last_changedtick when opening a buffer. (Hirohito Highlight,
closes#2742)
Problem: 'statusline' drops empty group with highlight change.
Solution: Do not drop an empty group if it changes highlighting. (Marius
Gedminas, closes#2228)
Problem: Changing StatusLine highlight while evaluating 'statusline' may
not change the status line color.
Solution: When changing highlighting while redrawing don't cause another
redraw. (suggested by Ozaki Kiichi, closes#2171, closes#2120)
Problem: FEAT_WINDOWS adds a lot of #ifdefs while it is nearly always
enabled and only adds 7% to the binary size of the tiny build.
Solution: Graduate FEAT_WINDOWS.
Problem: A terminal window with a running job behaves different from a
window containing a changed buffer.
Solution: Do not set 'bufhidden' to "hide". Fix that a buffer where a
terminal used to run is listed as "[Scratch]".
