Problem: linked_editing_range was still doing most of the capability
boilerplate itself.
Solution: refactor it to make use of the common Capability framework for
handling enabling, disabling, etc.
Patch 9.2.0306 fixed malformed lz4 extraction commands by using "tar -I lz4"
on Linux and leaving non-Linux tar implementations to auto-detect lz4 input.
That still fails on systems where tar does not support either -I lz4 or
automatic lz4 decompression, such as Solaris /usr/bin/tar.
Keep the existing Linux path using GNU tar's "-I lz4" support. For non-Linux
systems, use lz4 explicitly to decompress the archive to stdout and feed the
resulting tar stream to the configured tar extraction command. This is the
same style tar.vim already used for lz4 archives before patch 9.2.0306.

Problem:
:Man does not syntax highlight codeblocks (injected language).
Analysis:
init_pager() swapped pcall(parse_ref, ref) return values order, so
vim.b.man_sect was set to the manpage name instead of the section
number, so C syntax highlighting did not load.
Solution:
Swap the calls.
Today there is a constraint that these arguments to the enable filter be
mutually exclusive, but I do not know why such a constraint exists (it
is perfectly reasonable to want to enable a capabilility for just one
buffer and just one client).
Problem: [security]: s:NetrwLocalRmFile() escapes only the backslash in
the file name before passing it to :execute, so a name
containing "|" injects arbitrary Ex commands when the file is
deleted (cipher-creator)
Solution: Use fnameescape() to correctly escape the file name
(Yasuhiro Matsumoto).

This commit makes processing the erlangOperator and erlangBitType syntax
items faster.
- erlangOperator changes:
- Vim now parses erlangOperator faster because we define the operators
individually.
- The order of operators in erlangOperator had to be changed to make
the edge cases work the same as before (for example
erlangEqualsBinary).
- erlangBitType changes:
- Vim now parses erlangBitType faster because:
1. Now the long `\%(integer\|float\|...\)` sections are preceded by
"beginning of word" patterns (`\<`).
2. Now we use the old regexp engine (`\%#=1`).
Previously when an Erlang file contained long lines with erlangOperator
or erlangBitType patterns near the end, redrawing these lines was slow,
and typing at the end of the line was also slow.
For example, redrawing a 1787 characters long test line is now roughly
six times faster.

Problem:
an empty `{ isIncomplete = true, items = {} }` ends completion
instead of requerying.
Solution:
keep isIncomplete on empty lists and retrigger on keypress while incomplete.
Reset on <C-e> so it doesn't immediately re-query.
Problem: a font set via nvim_set_hl is lost or corrupted with font-only groups,
attribute combining, and update=true, and is dropped on any attr-table rebuild.
nvim__inspect_cell also frees the font name while a returned dict still borrows it.
Solution: register font-only groups, carry font through hl_combine_attr, inherit
it on update, and persist sg_font so a rebuild can restore it. Keep interned font
names across a rebuild instead of clearing them. Add the missing font field to
get_hl_info.

Problem: vim.diagnostic.Opts.VirtualLines.current_line and
vim.diagnostic.Opts.VirtualText.current_line cause redraw
on every CursorMoved event that makes the text jump
uncomfortably with rapid cursor movement.
Solution: `current_line` state is applied only on CursorHold,
while still being cleared on CursorMoved making it so that
until the cursor has stopped on a line, its diagnostic
looks like cursor is not on the line preventing flicker.
Problem:
This test is flaky since fff9897ce3 :

but if OSC 11 response arrives AFTER VimEnter, then

fix https://github.com/neovim/neovim/issues/40235
Problem: The refactor to use Capability left around some cruft and
semi-broken configuration for debounce.
Solution: Clean up now-unnecessary helper methods and simplify
deprecated ones to pass through to the non-deprecated ones. `debounce`
now defaults to 200 for all buffers but is overridable via the
deprecated start() method, which continues to take the max value
specified for any client attached to the buffer.
If we wish to expose changing the debounce in a non-deprecated way, we
will need to consider a "configuration" function, or even a bespoke
method to set the debounce time on the main metaclass (or provide
options to override for a particular buffer). General configuration of
specific LSP features is an as-of-yet unsolved problem.
Problem:
On some non-US keyboards, like Estonian/Swedish/etc, widely used []
characters in vim are hard to type. One way to overcome this is to use langmap
option to map accented characters, that are in the same place as [] on US
keyboards to []. Unfortunately this does not work currently in neovim, it
cannot map multibyte characters via langmap.
Solution:
The fix iterates over characters in typeahead and key buffers, instead of bytes,
in getchar.c handle_mapping(). It does not handle macros though, these tests are
still failing when turned on.

Problem:
Any random ftplugin or other autocmd, can throw an error when
`:checktime` reloads a buffer. This causes a trace which makes it look
like an issue with `autoread.lua`.

Solution:
Use pcall() and surface the error via nvim_echo.
Problem:
Old 'autoread' only did `:checktime` on focus-change and shell (":!")
commands, and only for non-hidden buffers. Since 'autoread' is now
driven by OS filewatcher events, buffers are updated much more eagerly.
This should be surfaced to the user somehow, either via a carefully
placed notification, or a minimal UI indicator.
A "notification" would be noisy, unless it is conditional on specific
circumstances (e.g. when "many" buffers are updated).
Solution:
Use the existing 'busy' buffer-local option as a subtle hint about
activity.
Problem: The semantic token module is using its own debounce timer for
the buffer on_lines event. If its internal debounce is shorter than the
changetracking module's debounce, it's possible for semantic token
requests to fire for changed buffers before the textDocument/didChange
notification is sent to the server.
Solution: Trigger semantic token requests from the LspNotify autocmd
when the method is the didChange or didOpen notifications, which
enforces a strict happens-before relationship for the sync change
notification followed by a semantic token request.
Note: There is still an internal debounce mechanism in the semantic
token module to handle other debouncing needs specific to its
functionality, such as debouncing server refresh notifications and
handling WinScrolled events when using range requests.
Problem: Keys valid in CTRL-X mode are never mapped while insert
completion is active, so <C-N> and <C-P> cannot be remapped
for completion started by complete().
Solution: Do not disable mappings in CTRL_X_EVAL mode. In this mode a
mapping cannot interfere with selecting the completion
method, which is what the no-mapping rule exists for.

Problem: The "%" command jumps to parens and braces inside comments,
unlike the "=" operator (cindent), which ignores them.
Solution: When 'comments' defines C-style comments and "%" is not in
'cpoptions', skip matching parens inside such comments, except
when the cursor is inside a comment so a match there can still
be found.

Problem: Running `vim.filetype.match()` when current working directory
was removed from disk throws a `vim.fs.abspath` assertion error.
However, the matching might still be possible without trying to match
against full path (like if it is a known extension).
Solution: Safely compute absolute path and ignore it if it errors.
Problem: Diagnostic virtual lines are hardcoded with "scroll" for
virt_lines_overflow option.
Solution: Add a `overflow` option to `virtual_lines` config
to support "wrap", "scroll", "trunc", and "auto".
Problem:
The 'autoread' option only checks for file changes reactively — on
FocusGained, :checktime, CmdlineEnter, etc. — by polling timestamps.
External changes are not detected until the user interacts with Neovim.
Solution:
Add a core module (runtime/lua/nvim/autoread.lua) enabled from
runtime/plugin/autoread.lua that watches each buffer's file using
vim._watch.watch() (libuv fs_event). On change detection it calls
:checktime, which invokes the existing buf_check_timestamp() logic
for reload/prompt handling. Watchers are managed via autocmds tied
to buffer lifecycle events and respect the 'autoread' option (global
and buffer-local).
- Explicitly match the dot accessor
- Exclude the qualifier when matching qualified function calls
The dot accessor lookbehind on builtin function calls was slow, matching
across expression based dictionary accessors was visually inconsistent,
and it's arguably more semantically correct.

Problem:
Flickering may occur when paging up/down in big files, as ranges for semantic
tokens are requested. This happens with LSP servers like gopls which return
"/full" semantic tokens if the file is too big, where we fall back to
viewport-range token retrievals.
Solution:
Broaden the requested ranges to one viewport of "overscan" on each side plus
some padding if possible:
(viewport_topline - viewport_height)..(viewport_botline + viewport_height)
Problem:
`nvim -u NONE -d <(xxd one) <(xxd two)` has weird behavior.
Process substitution `<(...)` is a pipe and not a seekable file.
Test case:
cat /dev/random | head -c 10240 > one
cp one two
cat /dev/random | head -c 10240 >> two
nvim -u NONE -d <(xxd one) <(xxd two)
Solution:
Workaround the issue by skipping `nvim.difftool` if the 2 args are not
directories; fall-through to the builtin diff handling.

Problem: unmarking a regular file when there are directories in the markings
list also removes the 2match highlight from those directories.

Problem:
A text edit positioned entirely past the last buffer line, with
newText ending in a newline, leaves a stray blank line: the
past-the-end path appends the trailing empty fragment produced by
vim.split() and does not set has_eol_text_edit, so the end-of-buffer
cleanup is skipped. Formatting servers emit such edits whenever
formatting moves text to the end of a document.
Regression from ec94014cd1 (#20137), which split the past-the-end
fast path off the clamp path that sets the flag.
Solution:
Set has_eol_text_edit in the past-the-end path, like the adjacent
path that clamps end_row.
Problem:
When a server sends workspace/codeLens/refresh while an automatic codelens
request is already scheduled, Nvim ignores the server refresh. This can leave
rendered codelens text stale until another buffer edit triggers a new request.
Solution:
Cancel the pending automatic request and send the server-requested refresh
immediately. This preserves request coalescing while giving explicit server
refreshes priority.
Problem:
* 'shellcmdflag' states that its default value is set according to the
value of 'shell', but this behavior is not yet implemented on Windows.
The same applies to 'shellpipe', 'shellredir', and 'shellxquote'.
* On Windows, Git is often installed in paths containing spaces, and we
still do not correctly resolve the sh executable name as described in
'shell'.
* On Windows, the default value of 'shellslash' is always `false`,
which causes Unix-like shells to interpret `\` in paths returned by
some functions as escape charaters.
Solution:
Use a simple rule table to detect common shells (e.g. `cmd`,
`powershell`, shells whose names contain `csh` or `sh`) and apply
best-effort defaults, while leaving more complex scenarios to user
configuration.
Problem: docs say {str} is capped at 256 and longer returns an empty list.
Solution: it's 1024, and {str} plus each candidate are just truncated to
that, not rejected; fix the text.

Problem: In command-line completion with a popup menu ('wildoptions'

with the mouse wheel in command-line mode as well, without
closing the completion popup menu.

Problem:
- `pos.cursor()` receives a table contains `row` and `col` as arguments,
but `pos:to_cursor` returns `row` and `col` directly
without wrapping them in a table.
- `pos.mark()`/`pos:to_mark` can already handle unpacked `row` `col`.
Solution:
Make `pos:to_cursor()` return a `row` and `col` in a table.
