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().

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: sidescrolloff and scrolloff options work slightly
different than other global-local options
Solution: Make it behave consistent for all global-local options
It was noticed, that sidescrolloff and scrolloff options behave
differently in comparison to other global-local window options like
'listchars'
So make those two behave like other global-local options. Also add some
extra documentation for a few special local-window options.
Add a few tests to make sure all global-local window options behave
similar

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.

Prepare for https://github.com/neovim/tree-sitter-vimdoc/pull/108 which improves
`{arg}` highlighting in many common cases:
vim.foo({bar})
vim.foo( {bar})
nvim_foo({bar})
nvim_foo({bar},{baz})
nvim_foo({bar}, {baz})
foo[{buf}]
The tradeoff is that things like `"[{"` are flagged as parse errors.
We could avoid if we drop support for `foo[{buf}]`, but that is rather common
(see `builtin.txt`).

Also:
- fix a missing `<` in builtin.txt.
- edit `:function` `{name}` wording to match the change made for the docs above
by Justin in #10619.
- link to `*vimrc*` rather than `*init.vim*` in repeat.txt change (as `init.lua`
may also be used).

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`.
libvterm v0.3 supports reflow of terminal buffer when Nvim is resized
Since v0.3 is now a required dependency, enable it by default to find
(and fix) possible issues.
Note: Neovim's scrollback buffer does not support reflow (yet), so lines
vanishing into the buffer due to a too small window will be restored
without reflow.
Problem: Some commands for opening a file don't use 'switchbuf'.
Solution: Use 'switchbuf' for more commands. (Yegappan Lakshmanan,
