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.

Problem: no max callback recursion limit
Solution: bail out, if max call recursion for callback functions
has been reached.
This checks the 'maxfuncdepth' setting and throws E169 when a callback
function recursively calls itself.

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.

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:
On Windows, "gf" fails on a filepath that has a line:column suffix.
Example:
E447: Can't find file "src/app/core/services/identity/identity.service.ts:64:23"
Solution:
- Remove ":" from 'isfname' on Windows. Colon is not a valid filename
character (except for the drive-letter).
- Handle drive letters specially in file_name_in_line().
Fixes#25160
Problem: cannot complete option values
Solution: Add completion functions for several options
Add cmdline tab-completion for setting string options
Add tab-completion for setting string options on the cmdline using
`:set=` (along with `:set+=` and `:set-=`).
The existing tab completion for setting options currently only works
when nothing is typed yet, and it only fills in with the existing value,
e.g. when the user does `:set diffopt=<Tab>` it will be completed to
`set diffopt=internal,filler,closeoff` and nothing else. This isn't too
useful as a user usually wants auto-complete to suggest all the possible
values, such as 'iblank', or 'algorithm:patience'.
For set= and set+=, this adds a new optional callback function for each
option that can be invoked when doing completion. This allows for each
option to have control over how completion works. For example, in
'diffopt', it will suggest the default enumeration, but if `algorithm:`
is selected, it will further suggest different algorithm types like
'meyers' and 'patience'. When using set=, the existing option value will
be filled in as the first choice to preserve the existing behavior. When
using set+= this won't happen as it doesn't make sense.
For flag list options (e.g. 'mouse' and 'guioptions'), completion will
take into account existing typed values (and in the case of set+=, the
existing option value) to make sure it doesn't suggest duplicates.
For set-=, there is a new `ExpandSettingSubtract` function which will
handle flag list and comma-separated options smartly, by only suggesting
values that currently exist in the option.
Note that Vim has some existing code that adds special handling for
'filetype', 'syntax', and misc dir options like 'backupdir'. This change
preserves them as they already work, instead of converting to the new
callback API for each option.

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.
Also fixes a warning in latest clang which didn't approve of
the funky math switch statement in append_arg_number
Problem:
Nvim docs use "•" as a list item prefix but `gw{motion}` doesn't format
such lists by default.
Solution:
Change the 'comments' option to include "fb:•" by default.
* docs(options): take ownership of options.txt
- `src/nvim/options.lua` is now the source of truth
- generate runtime/lua/vim/_meta/options.lua
* fixup! zeer comments
* fixup! zeer comments (2)
* fixup! re-enable luacheck
* fixup! regen
The options 'path', 'include', and 'define' all use C-specific default
values. This may have made sense a long time ago when Vim was mostly
used just for writing C, but this is no longer the case, and we have
ample support for filetype specific configuration. Make the default
values of these options empty and move the C-specific values into a
filetype plugin where they belong.

Problem:
Completion messages such as "scanning tags" are noisy and generally not
useful on most systems. Most users probably aren't aware that this is
configurable.
Solution:
Set `shortmess+=C`.
Problem: Cannot scroll by screen line if a line wraps.
Solution: Add the 'smoothscroll' option. Only works for CTRL-E and CTRL-Y
so far.

Problem:
On Windows, :make does not display the output of the program it runs.
The cause is the default 'shellpipe'. On Linux, nvim uses `tee` to redirect the
output to both stdout and the error file. In Windows, for both cmd.exe and
powershell, the output is only redirected to the error file.
Solution:
- On Windows, change the 'shellpipe' default to "2>&1| tee".
- Nvim includes `tee` in its Windows package.
- Document recommended defaults for powershell.
Fixes#12910
we cannot remove 'paste'. It is very common in plugins and configs.
'pastetoggle' can and should be removed though, it's a total waste of everyone's time because it generates bug reports and doesn't work well, and is useless because bracketed-paste works better.
This feature has long been obsolete. The 'keymap' option can be used
to support language keymaps, including hebrew and hebrewp (phonetic
mapping). There is no need to keep the old c code with hardcoded
keymaps for some languages.
Problem: Unable to customize the column next to a window ('gutter').
Solution: Add 'statuscolumn' option that follows the 'statusline' syntax,
allowing to customize the status column. Also supporting the %@
click execute function label. Adds new items @C and @s which
will print the fold and sign columns. Line numbers and signs
can be clicked, highlighted, aligned, transformed, margined etc.
This is needed for #18375 for the obvious reasons.
note: verbose_terminfo_event is only temporarily needed
until the full TUI process refactor is merged.

With #20374 tabline option is marked with 'statuslines' redraw flag.
But 'statuslines' doesn't redraw tabline. As a result, tabline doesn't
get redrawn when tabline option is set and statuslines get unnecessarily redrawn.
This patch fixes the issue by adding a new redraw flag P_RTABL to redraw
tabline.
