Add a minimal ftplugin `runtime/ftplugin/yara.vim` that sets:
- `commentstring` for YARA line comments (`//`)
- `comments` for YARA block comment (`/* */`)
- `formatoptions` to wrap comment lines and continue comment after newlines
This was heavily inspired from `runtime/ftplugin/c.vim`

Problem:
`nvim_echo(…, {id=…})` accepts user-defined id as a string or integer.
Generated ids are always higher than last highest msg-id used. Thus
plugins may accidentally advance the integer id "address space", which,
at minimum, could lead to confusion when troubleshooting, or in the
worst case, could overflow or "exhaust" the id address space.
There's no use-case for it, and it could be the mildly confusing, so we
should just disallow it.
Solution:
Disallow *integer* user-defined message-id.
Only allow *string* user-defined message-id.
Problem:
nvim_get_option_value with "filetype" set silently returns incorrect
defaults if autocommands are blocked, like when they're already running.
Solution:
Allow its FileType autocommands to nest: `do_filetype_autocmd(force=true)`.
Also error if executing them fails, rather than silently return wrong defaults.
Endless nesting from misbehaving scripts should be prevented by the recursion
limit in apply_autocmds_group, which is 10.
Problem:
On windows, if a drive-relative path doesn't contain a slash,
`path_to_absolute` can't split out the relative component, causing
expansion to fails. e.g., `c:` `c:.` `c:..` `c:foo.md`
Solution:
For these cases, we can pass letter and colon to `path_full_dir_name`.
Notably, `..` is included as well.
if that relative path exists, it can be expanded correctly.
Problem:
When `to_vim_value[info.metatype](info, value)` is called, a list value
such as `{'eob:a'}` is treated like a map, which generates `1:eob:a`.
Note: commands like `:lua vim.opt.wildmode={'longest:full'}` are not an
issue because only cases harcoded in `key_value_options` have metatype `map`.
Solution:
Check for array type and use the same logic as in array metatypes.
Problem:
Right-click menu fails with E335 when using V in Insert mode (after
i_ctrl-o). The mode detection checks restart_edit before VIsual_active,
incorrectly selecting Insert mode binding even when Visual mode is
active.
Solution:
Check Visual mode before Insert mode, to match get_menu_mode() priority
order.
Problem:
When code lens is enabled, `on_attach` is executed, but it does not trigger a redraw. Another event, eg, moving the cursor, is required to trigger a redraw and execute the decoration provider's `on_win`.
Solution:
Trigger a `redraw` after each request is completed.
Problem:
"[Process exited]" is implemented in C with anonymous namespace
and users have no way to hide it.
Solution:
- Handle "TermClose" event in Lua.
- User can delete the "nvim.terminal" augroup to avoid "[Process exited]".
Problem:
Building with GCC emits -Wfree-nonheap-object warnings in lua_cjson code
when calling strbuf_free(), despite the free being conditionally valid.
This is an unresolved GCC issue: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=98753
Solution:
Supress warnings with the -Wno-free-nonheap-object flag for now.
Problem:
Applications running inside :terminal that use DEC private mode 2026
(synchronized output) to batch screen updates get garbled rendering.
Neovim's embedded libvterm does not handle mode 2026, so the
synchronization sequences are ignored and intermediate screen states
leak through as visual corruption.
Solution:
Add mode 2026 support to libvterm's state machine and wire it through
to terminal.c. When an application enables mode 2026, invalidation of
the terminal buffer is deferred until the application disables it,
causing all accumulated screen updates to flush as a single
atomic refresh.
* fix(terminal): harden sync output redraw gating
Problem:
The initial mode 2026 implementation gated invalidate_terminal()
but missed three other redraw paths: term_sb_push/term_sb_pop
bypassed the gate by directly adding to invalidated_terminals,
refresh_timer_cb could fire mid-sync flushing partial state, and
the 10ms timer delay after sync-end left a window for stale
repaints.
Solution:
- Gate term_sb_push/term_sb_pop during synchronized output
- Skip syncing terminals in refresh_timer_cb
- On sync end, schedule a zero-delay full-screen refresh via
sync_flush_pending flag in terminal_receive()
- Add news.txt entry for mode 2026 support

* test(terminal): add vterm unit tests for mode 2026
Add unit-level tests for synchronized output (mode 2026) to
vterm_spec.lua, covering settermprop callbacks and DECRQM
query/response.

* fix(terminal): address review feedback for mode 2026
- Use multiqueue_put(main_loop.events) instead of restarting the
global refresh timer on sync end, to avoid affecting other
invalidated terminals.
- Add screen:expect_unchanged() to verify screen doesn't update
during sync mode.
- Merge buffer-lines test into existing test.

Problem:
Completion preview always assumes plain text, ignoring LSP documentation "kind".
Solution:
Pass markup kind from completion item to info window, or fallback to PlainText.
Problem: 'jumpoptions' "view" doesn't remember skipcol and may lead to
glitched display with 'smoothscroll'.
Solution: Save skipcol in the mark view. Also make sure skipcol doesn't
exceed line size.
vim-patch:9.2.0174: diff: inline word-diffs can be fragmented
Problem: When using 'diffopt=inline:word', lines were excessively
fragmented with punctuation creating separate highlight
blocks, making it harder to read the diffs.
Solution: Added 'diff_refine_inline_word_highlight()' to merge
adjacent diff blocks that are separated by small gaps of
non-word characters (up to 5 bytes by default) (HarshK97).
When using inline:word diff mode, adjacent changed words separated by
punctuation or whitespace are now merged into a single highlight block
if the gap between them contains fewer than 5 non-word characters.
This creates more readable diffs and closely matches GitHub's own diff
display.

Problem: possible crash with winminheight=0
(Emilien Breton)
Solution: Use <= instead of < when checking reserved room in
frame_setheight() to correctly handle the zero-height
boundary case (Hirohito Higashi).
In frame_setheight(), when shrinking the current window and the only
other window has 'winfixheight' with 'winminheight'=0, room_reserved
was not cleared because the condition used '<' instead of '<='.
The freed rows were discarded, leaving fr_height sum less than
topframe fr_height. Subsequent resize operations then computed a
wrong room_cmdline that expanded topframe beyond the screen, causing
a crash.

Problem:
The 'android' and 'termux' feature flags have been shipped in the
downstream neovim/neovim-nightly package for 5+ years but were never
properly documented in the downstream patch.
Solution:
Upstream the 'android' and 'termux' feature flags into Neovim as
decoupled feature flags, this enables the 'android' feature in
particular to be available independently of the 'termux' feature
for builds of Neovim against the Android NDK, but not including
the Termux NDK patchset.

Problem: autocmds that switch windows may cause them to remain with
w_locked set, preventing them from being closed longer than
intended.
Solution: Unset w_locked in the window where it was set (Sean Dewar).
closes: vim/vim#19716bae31c35bb
Also move alist_add_list's ga_grow inside the if block, so it's only called when
check_arglist_locked is OK, like Vim.
I also notice a redundant return at the end of the block; could be useful if
more code is added later, so I'm leaving it.
Problem:
No way to disable progress messages in cmdline message area. If
a third-party plugin handles Progress events + messages, the user may
not want the "redundant" progress displayed in the cmdline message area.
Solution:
Support "progress:c" entry in 'messageopts' option.
Problem:
The `float` field of vim.diagnostic.config can be a function,
but diagnostic.open_float() does not handle it correctly.
Solution:
Add handling for it in open_float().
Problem: nvim_open_tabpage's "enter" argument is optional, which is inconsistent
with nvim_open_win.
Solution: make it a (non-optional) positional argument, like nvim_open_win.
Also change "enter"'s description to be more like nvim_open_win's doc.
Problem: "after" in nvim_open_tabpage is inconsistent with how a count works
with :tab, :tabnew, etc. Plus, the name "after" implies it's inserted after that
number.
Solution: internally offset by 1. Allow negative numbers to mean after current.
Hmm, should we even reserve sentinels for after current? Callers can probably
just use nil...
- Cleanup, remove redundant comments, add more tests.
- Enhance win_new_tabpage rather than create a new function for !enter, and use
a different approach that minimizes side-effects. Return the tabpage_T * and
first win_T * it allocated.
- Disallow during textlock, like other APIs that open windows.
- Remove existing win_alloc_firstwin error handling from win_new_tabpage; it's
not needed, and looks incorrect. (enter_tabpage is called for curtab, which is
not the old tabpage! Plus newtp is not freed)
- Fix checks after creating the tabpage:
- Don't fail if buf wasn't set successfully; the tab page may still be valid
regardless. Set buffer like nvim_open_win, possibly blocking Enter/Leave
events. (except BufWinEnter)
- tp_curwin may not be the initial window opened by win_new_tabpage. Use the
win_T * it returns instead, which is the real first window it allocated,
regardless of autocmd shenanigans.
- Properly check whether tab page was freed; it may have also been freed
before win_set_buf. Plus, it may not be safe to read its handle!
that was an internal note which somehow slipped in months ago and even
survived the change to Vimscript9

Problem:
"Sorry" in a message (1) is noise, and (2) actually reduces the clarity
of the message because the titlecasing of "Sorry" distracts from the
actually important part of the message.
Solution:
Drop "Sorry" from messages.
Problem: termdebug :Break does not support `thread` and `if` arguments

- mark Test_termdebug_basic() as flaky in oldtest termdebug plugin tests
The Test_termdebug_config_types() part does not apply here.

- guard balloon_show() in the termdebug plugin
- wait for g:termdebug_is_running in Test_termdebug_basic()

- Functions are way too long. Readability and maintainability should
be slightly improved.
- Some variables are re-assigned to their initial value at teardown.
This should not be needed since all internal variables are
re-initialized at startup of every Termdebug session.
Only include:
- prompt-mode buffer tracking changes around `promptbufnr`
- prompt buffer cleanup in `CloseBuffers()` and `EndDebugCommon()`
- related `BufUnload` and gdb startup failure cleanup adjustments
The remaining upstream `StartDebug_term()` refactor and helper extraction
do not apply here.

For ASM and Variables buffer, check were done to make sure they existed
before attempting to close them, but not for debugged program or gdb
communication. The debugged program window is a user-facing one and
user might close it manually, so it's better to check if it exists.

Problem: #38316 is a bit aggressive; we need not always leave Terminal mode if
autocmds put us in a different terminal.
Solution: don't skip entering; let terminal_check_focus handle whether we should
immediately leave.
Problem:
`K` in help files may fail in some noisy text. Example:
(`fun(config: vim.lsp.ClientConfig): boolean`)
^cursor
Solution:
- `:help!` (bang, no args) activates DWIM behavior: tries `<cWORD>`,
then trims punctuation until a valid tag is found.
- Set `keywordprg=:help!` by default.
- Does not affect `CTRL-]`, that is still fully "tags" based.
Problem: heap-use-after-free possible when entering Terminal mode if
autocommands close the terminal.
Solution: set the refcount. Skip to the end if we must close the terminal.
