The 'termsync' option enables a mode (provided the underlying terminal
supports it) where all screen updates during a redraw cycle are buffered
and drawn together when the redraw is complete. This eliminates tearing
or flickering in cases where Nvim redraws slower than the terminal
redraws the screen.
Problem: recursive callback may cause issues on some archs
Solution: Decrease the limit drastically to 20
Recursive callback limit causes problems on some architectures
Since commit 47510f3d6598a1218958c03ed11337a43b73f48d we have a test
that causes a recursive popup callback function to be executed. However
it seems the current limit of 'maxfuncdepth' option value is still too
recursive for some 32bit architectures (e.g. 32bit ARM).
So instead of allowing a default limit of 100 (default value for
'maxfuncdepth'), let's reduce this limit to 20. I don't think there is a
use case where one would need such a high recursive callback limit and a
limit of 20 seems reasonable (although it is currently hard-coded).

Problem: statusline may look different than expected
Solution: do not check for highlighting of stl and stlnc characters
statusline fillchar may be different than expected
If the highlighting group for the statusline for the current window
|hl-StatusLine| or the non-current window |hl-StatusLineNC| are cleared
(or do not differ from each other), than Vim will use the hard-coded
fallback values '^' (for the non-current windows) or '=' (for the
current window). I believe this was done, to make sure the statusline
will always be visible and be distinguishable from the rest of the
window.
However, this may be unexpected, if a user explicitly defined those
fillchar characters just to notice that those values are then not used
by Vim.
So, let's assume users know what they are doing and just always return
the configured stl and stlnc values. And if they want the statusline to
be non-distinguishable from the rest of the window space, so be it. It
is their responsibility and Vim shall not know better what to use.

Problem: No way to have extmarks automatically removed when the range it
is attached to is deleted.
Solution: Add new 'invalidate' property that will hide a mark when the
entirety of its range is deleted. When "undo_restore" is set
to false, delete the mark from the buffer instead.
When the terminal emulator sends an OSC sequence to Nvim (as a response
to another OSC sequence that was first sent by Nvim), populate the OSC
sequence in the v:termresponse variable and fire the TermResponse event.
The escape sequence is also included in the "data" field of the
autocommand callback when the autocommand is defined in Lua.
This makes use of the already documented but unimplemented TermResponse
event. This event exists in Vim but is only fired when Vim receives a
primary device attributes response.

Problem: trim(): hard to use default mask (partly revert v9.0.2040)
Solution: use default mask when it is empty
The default 'mask' value is pretty complex, as it includes many
characters. Yet, if one needs to specify the trimming direction, the
third argument, 'trim()' currently requires the 'mask' value to be
provided explicitly.
Currently, an empty 'mask' will make 'trim()' call return 'text' value
that is passed in unmodified. It is unlikely that someone is using it,
so the chances of scripts being broken by this change are low.
Also, this reverts commit 9.0.2040 (which uses v:none for the default
and requires to use an empty string instead).

'v:none' is already used to mean "use the default argument value" in

Problem: [security] use-after-free with wildmenu
Solution: properly clean up the wildmenu when exiting
Fix wildchar/wildmenu/pum memory corruption with special wildchar's
Currently, using `wildchar=<Esc>` or `wildchar=<C-\>` can lead to a
memory corruption if using wildmenu+pum, or wrong states if only using
wildmenu. This is due to the code only using one single place inside the
cmdline process loop to perform wild menu clean up (by checking
`end_wildmenu`) but there are other odd situations where the loop could
have exited and we need a post-loop clean up just to be sure. If the
clean up was not done you would have a stale popup menu referring to
invalid memory, or if not using popup menu, incorrect status line (if
`laststatus=0`).
For example, if you hit `<Esc>` two times when it's wildchar, there's a
hard-coded behavior to exit command-line as a failsafe for user, and if
you hit `<C-\><C-\><C-N>` it will also exit command-line, but the clean
up code would not have hit because of specialized `<C-\>` handling.
Fix Ctrl-E / Ctrl-Y to not cancel/accept wildmenu if they are also
used for 'wildchar'/'wildcharm'. Currently they don't behave properly,
and also have potentially memory unsafe behavior as the logic is
currently not accounting for this situation and try to do both.
(Previous patch that addressed this: vim/vim#11677)
Also, correctly document Escape key behavior (double-hit it to escape)
in wildchar docs as it's previously undocumented.
In addition, block known invalid chars to be set in `wildchar` option,
such as Ctrl-C and `<CR>`. This is just to make it clear to the user
they shouldn't be set, and is not required for this bug fix.

runtime(doc): Improve command-line completion docs (vim/vim#13331)
* Improve command-line completion docs
Add more details about 'ignorecase' and its effect on cmdline
completion.
Make sure keys used in wildmenu are properly documented and linked in the
keys' documentation entries, and in `:h index` for proper
cross-referencing, as wildmenu popup is slightly different from
insert-mode popup menu.
* Fix docs typos

Problem: When clicking in the middle of a TAB, getmousepos() returns
the column of the next char instead of the TAB.
Solution: Break out of the loop when the vcol to find is inside current
char. Fix invalid memory access when calling virtcol2col() on
an empty line.

Problem: cmdline-completion for comma-separated options wrong
Solution: Fix command-line expansions for options with filenames with
commas
Fix command-line expansions for options with filenames with commas
Cmdline expansion for option values that take a comma-separated list
of file names is currently not handling file names with commas as the
commas are not escaped. For such options, the commas in file names need
to be escaped (to differentiate from a comma that delimit the list
items). The escaped comma is unescaped in `copy_option_part()` during
option parsing.
Fix as follows:
- Cmdline completion for option values with comma-separated file/folder
names will not start a new match when seeing `\\,` and will instead
consider it as one value.
- File/folder regex matching will strip the `\\` when seeing `\\,` to
make sure it can match the correct files/folders.
- The expanded value will escape `,` with `\\,`, similar to how spaces
are escaped to make sure the option value is correct on the cmdline.
This fix also takes into account the fact that Win32 Vim handles file
name escaping differently. Typing '\,' for a file name results in it
being handled literally but in other platforms '\,' is interpreted as a
simple ',' and commas need to be escaped using '\\,' instead.
Also, make sure this new logic only applies to comma-separated options
like 'path'. Non-list options like 'set makeprg=<Tab>' and regular ex
commands like `:edit <Tab>` do not require escaping and will continue to
work.
Also fix up documentation to be clearer. The original docs are slightly
misleading in how it discusses triple slashes for 'tags'.

Problem:
The swapfile "E325: ATTENTION" dialog is displayed when editing a file
already open in another (running) Nvim. Usually this behavior is
annoying and irrelevant:
- "Recover" and the other options ("Open readonly", "Quit", "Abort") are
almost never wanted.
- swapfiles are less relevant for "multi-Nvim" since 'autoread' is
enabled by default.
- Even less relevant if user enables 'autowrite'.
Solution:
Define a default SwapExists handler which does the following:
1. If the swapfile is owned by a running Nvim process, automatically
chooses "(E)dit anyway" (caveat: this creates a new, extra swapfile,
which is mostly harmless and ignored except by `:recover` or `nvim -r`.
2. Shows a 1-line "ignoring swapfile..." message.
3. Users can disable the default SwapExists handler via `autocmd! nvim_swapfile`.
A lot of updated places in the docs were already incorrect since long
since they did not reflect the default behaviour.
"[dos format]" could've been argued being better for discoverability
but that ship has already sailed as it is no longer displayed by default.
The "f" flag was removed in f7da472257.
The value of the "f" flag is no longer listed in the 'shortmess'
description and it cannot be disabled, so having it in the default value
is pointless and confusing.
Not everything needs to be crazy overconfigurable.
