Add a guarded "C++ 26 extensions" block (cpp_no_cpp26) covering new
lexical surface introduced since C++23:
- [[ ... ]] attributes as a region, so P3394 annotations carrying a
value expression (eg [[=foo{1}]]) no longer trip cErrInBracket on
their braces/parens. A \w\@1<! look-behind keeps it from matching a
subscripted immediately-invoked lambda (arr[[]{...}()]).
- ^^ reflection operator (P2996).
- [: :] splice brackets (P2996).
- contract_assert keyword (P2900).
Add input/cpp_cpp26.cpp exercising these constructs with screendumps,
and update dumps/cpp_noreturn_00.dump for the new [[ ]] attribute
delimiter highlighting.

Problem: Terminal background and truecolor detection runs only at startup,
gated on a UI being attached. A headless server has no UI then, so
`'background'` and `'termguicolors'` are never detected and remote
UIs ignore the terminal's theme.
Solution: Also (re)detect on UIEnter. The most recently attached terminal
wins; an explicit user value is preserved.
Problem: LspNotify never passed a buffer when executing the autocmds, so
buffer-local LspNotify autocmd subscriptions didn't have the correct buf
in the event metadata. It was also wrapped in a schedule() so the actual
autocmd was delayed until after the event loop.
This could result in the wrong buffer receiving the notification if
multiple LspNotify autocmds with buffer filters were added. Only the
"latest" one would actually receive non-buffer-filtered autocmds, not
the matching one. It also caused listeners to receive the notification
"out of sync" with when the notification is actually sent. If a buffer
is being deleted (which fires a textDocument/didClose notification), the
notification is scheduled and fired after the buffer is already gone.
Solution: For LSP notifications that pertain to a particular buffer, set
it when executing the LspNotify autocmds so the callback functions that
are filtered on that buffer will get the correct notifications and the
metadata buf field will be correct. Additionally, there is no need to
wrap the LspNotify callback in vim.schedule when it can be called inline
when the notification to the rpc server is fired.
This is tested by removing now-unnecessary autocmds from semantic tokens
(InsertEnter and BufWinEnter should no longer be necessary now that
requests are fired by LspNotify). Without this fix, simply modifying a
buffer doesn't actually trigger LspNotify correctly, and the test for
that fails.
Problem:
- Current 'statuscolumn' click label caveat is restrictive.
- v:virtnum is not unique to a line if it has both above and
below virtual lines.
- 'statuscolumn' click handler may expect v:virt/lnum to be set.
Solution:
- Store per-row click definitions for the statuscolumn in a
(nested line/virt number) map.
- Implement strategy that gives each 'statuscolumn' row a unique
v:virtnum.
- Set v:virt/lnum when determining which line is clicked.
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.
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:
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: 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: 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).
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: Extmark has support for horizontal scrolling and truncating, but not wrapping.
Solution: Extend virt_lines_overflow flags to support "wrap" and "auto" based on proposed changes in #18282.
Problem: In command-line completion with a popup menu ('wildoptions'
contains "pum"), the info popup shown next to the menu could
not be scrolled, unlike the Insert mode completion info popup
which scrolls with the mouse wheel.
Solution: When the mouse pointer is on top of the info popup, scroll it
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.
Problem:
`vim.pos.cursor(vim.api.nvim_get_current_buf(win), vim.api.nvim_win_get_cursor(win))`
is too verbose to create a cursor position of a window,
but it is a common use case.
Solution:
Overload `vim.pos.cursor()`, so that it accepts `win` as an argument when `pos` is omitted.
Problem:
The comma form of 'winborder' is split with copy_option_part(),
whose skip_to_option_part() eats spaces after a comma, and empty
fields are rejected.
Solution:
Split the comma form literally on ',', keeping empty fields and
single-space fields.
This was originally used because we needed a lua interpreter to run the
standalone _busted_ lua application (except we used fuckery behind the
scenes to fake its binary dependencies with our own binary
dependencies). Now we longer do that, we instead run `test.harness` as a
standard nvim -l script. as this mode is no longer used in tests it
risks going to bitrot anyway.
NB: -ll mode still had some theoretical benefits like quicker
initialization and more "native" printing behavior, etc.
But we can incrementally work on "nvim -l" mode instead
of maintaining a separate special thing.
Problem:
This doc on `vim.lsp.completion.get()`:
--- Used by the default LSP |omnicompletion| provider |vim.lsp.omnifunc()|, thus |i_CTRL-X_CTRL-O|
--- invokes this in LSP-enabled buffers. Use CTRL-Y to select an item from the completion menu.
--- |complete_CTRL-Y|
...makes two wrong claims:
1. "Used by the default LSP omnicompletion provider vim.lsp.omnifunc()"
- `_omnifunc` does not call `M.get()`, it calls the internal `trigger()` directly.
2. "thus |i_CTRL-X_CTRL-O| invokes this in LSP-enabled buffers"
- The two paths use different client sets:
- `M.get()` reads `buf_handles[bufnr].clients` (clients
explicitly registered via `vim.lsp.completion.enable(true, ...)`).
- `_omnifunc` reads `lsp.get_clients({method='textDocument/completion'})` (every
completion client, regardless of `enable()`).
Solution:
Update docs.

Problem:
Diagnostic highlight groups were applied by iterating and calling
`vim.hl.range` for each group individually. That resulted in multiple
extmarks with the same priority being created separately, which does not
allow `DiagnosticUnnecessary` and `DiagnosticDeprecated` with matching
options override `Diagnostic*` styling.
Solution:
Pass the list of hl-groups to `vim.hl.range` so they are applied
together in the correct order.

Problem: Several Vim9 keywords lack EX_WHOLE and can be shortened in
Vim9 script, inconsistent with endif/enddef/endfor/endwhile/
endtry which already have it. The error from :endd in a
nested function also hardcodes "enddef" instead of reporting
what the user typed. fullcommand("ho") returns "horizontal"
even though :ho is below the documented 3-char minimum.
Solution: Add EX_WHOLE to :class, :def, :endclass, :endinterface,
:endenum, :public and :static. In get_function_body() pass
the user-typed command to the error message. Force :ho to
CMD_SIZE in find_ex_command() so fullcommand() reflects the
modifier minimum. Extend tests and documentation accordingly

Problem:
It is repetitive to map multiple keymaps to do the same thing. Here are some
cases where being able to do this would be useful:
-- Visual movement for both j/k and down/up:
vim.keymap.set({ 'n', 'x' }, { 'j', '<Down>' }, 'v:count == 0 ? "gj" : "j"', { expr = true })
vim.keymap.set({ 'n', 'x' }, { 'k', '<Up>' }, 'v:count == 0 ? "gk" : "k"', { expr = true })
-- Map multiple keys to `<Nop>` concisely:
vim.keymap.set({ 'n', 'x' }, { '<Leader>', '<Localleader>', '<CR>' }, '<Nop>')
-- Remove multiple keymaps at once:
vim.keymap.del('n', { 'gri', 'grn', 'grr' })
Solution:
Support the `lhs` of `vim.keymap.set()` and `vim.keymap.del()` being a table, in
the same way that `modes` can be.
