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.
Fixes: https://github.com/neovim/neovim/issues/25856
It is a design goal of extmarks that they allow precise tracking
of changes across undo/redo, including restore the exact positions
after a do/undo or undo/redo cycle. However this behavior is not useful
for all usecases. Many plugins won't keep marks around for long after
text changes, but uses them more like a cache until some external source
(like LSP semantic highlights) has fully updated to changed text and
then will explicitly readjust/replace extmarks as needed.
Add a "undo_restore" flag which is true by default (matches existing
behavior) but can be set to false to opt-out of this behavior.
Delete dead u_extmark_set() code.
connection from any channel or stdio will unblock
remote_ui_wait_for_attach. Wait on stdio only if

Problem: Currently there is no way of customizing behavior of
`declaration`, `definition`, `typeDefinition`, and `implementation`
methods in `vim.lsp.buf` when LSP server returns `Location`. Instead,
cursor jumps to that location directly.
Solution: Normalize LSP response to be `Location[]` for those four cases.
While the interfaces for setting number and boolean options are now unified by #25394, there is still a separate `set_string_option` function that is used for setting a string option. This PR removes that function and merges it with set_option.
BREAKING CHANGE: `v:option_old` is now the old global value for all global-local options, instead of just string global-local options. Local value for a global-local number/boolean option is now unset when the option is set (e.g. using `:set` or `nvim_set_option_value`) without a scope, which means they now behave the same way as string options.

The prefix option of the diagnostic virtual text can be a function,
but previously it was only a function of diagnostic.
This function should also have additional parameters index and total,
more consistently and similarily as in the prefix function for
`vim.diagnostic.open_float()`.
These additional parameters will be useful when there are too many
number of diagnostics in a single line.

matchparen: do not use hard-coded match id (vim/vim#13393)
* matchparen: do not use hard-coded match id
Instead of using the hard-coded match id 3, which may also be used by
other plugins, let the matchparen plugin use whatever ids are
automatically returned when calling matchaddpos().
For backwards-compatibility, keep the `:3match` call, which will still
use the hard-coded id 3 (as mentioned in :h :3match).

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).

The default 'mask' value is pretty complex, as it includes many

'v:none' is already used to mean "use the default argument value" in
user defined functions. See |none-function_argument| in help.

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.

BREAKING CHANGE: This breaks the OptionSet autocommand, as the `v:` values associated with it (`v:option_new`, `v:option_old`, `v:option_oldlocal` and `v:option_oldglobal`) are now the same type as the option, instead of all option values being converted to strings.

`is_pull` should be optional, otherwise it is an API change that
introduces warnings in consumers.
Also fixes the type annotation of `_client_pull_namespaces` where the
key is a string.
Problem: Certain compilers (primarily GCC) do not recognize an exhaustive enum switch statement as being exhaustive. This manifests in the form of compiler errors in exhaustive switch statements where each case has a return statement but there isn't a catch-all return statements. These compiler errors are spurious in the context of the Neovim codebase. So #25533 added the `UNREACHABLE` macro to denote apart of the code that's unreachable, which was used after every such switch statement to tell the compiler to treat the switch statement as exhaustive. However, the macro is mentioned nowhere in the style guide,and new contributors would not have any natural way of learning about it as it stands now. This would lead to confusion when they inevitably encounter one of these compiler errors.
Solution: Add a style guideline which shows how to use the `UNREACHABLE` macro to fix these compiler errors.
Problem: The style guide states that all switch statements that are not conditional on an enum must have a `default` case, but does not give any explicit guideline for switch statements that are conditional on enums. As a result, a `default` case is added in many enum switch statements, even when the switch statement is exhaustive. This is not ideal because it removes the ability to have compiler errors to easily detect unchanged switch statements when a new possible value for an enum is added.
Solution: Add explicit guidelines for switch statements that are conditional on an enum, clarifying that a `default` case is not necessary if the switch statement is exhaustive. Also refactor pre-existing code with unnecessary `default` cases.
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 style guide currently recommends having a `default:` case for switch statements that are not conditional on an enumerated value. Additionally, it recommends using `assert(false)` if `default:` is unreachable. This is problematic because `assert()` only runs on debug builds, which may lead to confusing breakages in release builds. Moreover, this suggestion is followed nowhere in the C code and `abort()` is used everywhere instead.
Solution: Suggest using `abort()` instead of `assert(false)`, that way the program always terminates if a logically unreachable case is reached.
