Problem: With 'wildmode' set to list:full the matches are listed but the
wildmenu is not shown, although it is "full" that starts
wildmenu mode (zeertzjq).
Solution: List the matches and show the menu, as the two behaviors in
the same phase ask for. The menu is left to the phases that
ask for it, so that "list" on its own still only lists

Problem: popup_show() from a CmdlineChanged autocommand doesn't update
the screen (Mao-Yining)
Solution: Refresh the screen when popups need redraw
(Yasuhiro Matsumoto).
popup_settext()/popup_show() called from a CmdlineChanged autocommand
did not refresh the screen because cmdline mode normally skips
update_screen(), so async info-popup updates only became visible after
a manual :redraw. Refresh the screen when popups need redrawing right
after the autocommand.

fix(tui): emit ui_send output atomically with the frame
Problem:
tui_ui_send() writes directly to the TTY, bypassing the output buffer.
Sequences sent via nvim_ui_send() (e.g. kitty multiple-cursors, or
visual-dot-repeat) always arrive in a separate TTY write from the frame
they were computed for. This manifests as "tearing", or e.g. in the case
of multicursor the terminal renders text with stale cursor overlays.
Solution:
- tui_ui_send(): while a frame is being assembled (pending invalid
regions or buffered output), buffer instead of writing directly.
- Out-of-frame sends (tty queries, clear-on-disable) still write
immediately.
- mcursor.lua: emit the terminal-cursor update at the end of the redraw
cycle (`on_end`, when screen positions are final) instead of
vim.schedule().
Problem: A completion asked for with CTRL-X CTRL-O while
'autocompletedelay' is running is given the look of an
automatic one, the implicit "noselect" among it.
Solution: Turn autocompletion off where a typed key takes the completion
over. A completion already on screen goes on being what it
was (Hirohito Higashi).

Problem:
Undo places the cursor wherever the cursor happened to sit at "save
time" (`uh_cursor` is sampled lazily on the first change).
Examples:
- `i` preserves, but `a` does not
- `diw`, `atest<Esc>`, `d^` abandon the original position
- `D`, `o` restore it (by accident).
Solution:
`composite` tracks the pending atom (and its `origin`) across frames.
A `stuffed` continuation frame inherits the `origin` + prepped redo.
Store `origin` info in the undo header, so undo can restore it.
- Not for a mid-command undo break (i_CTRL-G_u).
- Undoing a mapping restores where the mapping started (which
technically may be different than where the "edit" started).
Problem: A function used through 'omnifunc' or 'complete' is called the
same way whether 'autocomplete' started the completion or a
key asked for one, so it cannot answer differently.
Solution: Report which of the two it is in complete_info() as "auto". It
is returned only when asked for in {what}, so what
complete_info() says by itself does not change
(Hirohito Higashi).

Problem: backupcopy=auto overwrites a file in place when umask is restrictive.
The probe treats permission restore as impossible and writes in
place, keeping the same inode.
Solution: When creating the probe file, open() applies umask, so a 0644
file becomes 0600 with umask 0077. Use fchmod() to fix the
permissions of the probe (Pranav Dwivedi).

Problem:
Parent commit regressed some behavior of the old C helptags-gen impl:
- helpfiles in sub-directories are named by basename, so :help fails
- "help-tags" always names "tags", never "tags-nl"
- E150 E151 E152 E153 are never reported
- existing tags file is not overwritten if no tags were found
- a duplicate tag aborts the run, skipping the remaining directories
- `*.TXT` and `*.FRX` (uppercase) are not recognized as helpfiles
- tree-sitter-vimdoc accepts tags that the C parser rejected: `*a|b*`
(breaks |links|) and unterminated `*tag`
- PUC Lua "<" compares with (localized) `strcoll()`, so the tags file is
not sorted by byte value (E432)
- requiring `vim.treesitter` at load time breaks :help itself, not just
:helptags, where the module is unavailable
- `vim.pack` runs :helptags for plugins that have no "doc/" directory,
so every install/update emits E150
Solution:
- Fail the build if generating helptags reports any `v:errmsg`.
- Restore old behavior: tags generated for runtime/doc are now identical
to those from the C implementation. Errors are non-fatal messages
instead of exceptions, so all directories are still processed.
- Load treesitter lazily, report a plain error if parser is missing.
Problem:
In order for ui2 to graduate to the main "messages ui" its configuration
needs to graduate into actual options.
Solution:
Migrate some of its config to 'messagesopt':
- "maxheight" (note: currently this is an integer treated as
a "percentage"; if we want to support a row count we could allow
values with units, like `"42%"`)
- "pager"
- "timeout"
Also improves error messages:
messagesopt=hit-enter,history:500,bogus E474: Unknown item 'bogus'
messagesopt=hit-enter,history:500,progress:x E474: 'progress' must be one of: , c
messagesopt=hit-enter,history:abc E474: 'history' requires a number
Problem: complete_info() omits "abbr_hlgroup" and "kind_hlgroup".
Solution: Keep the highlight group ID with the match instead of the
resolved attribute and add both entries to the returned items
(glepnir).

Problem: In the debugger ">up" and ">frame" select an older function call
frame, but get_funccal_local_ht() and the related functions check
current_funccal while returning a dictionary of the frame that
get_funccal() selected. A :def function keeps its local variables
on the vim9 stack, its funccall_T has no l: and a: dictionaries and
is allocated cleared, so with such a frame selected the returned
hashtab has a NULL ht_array and evaluating any variable name at the
debug prompt crashes in hash_lookup().
Solution: Check the funccal that is actually used and return NULL when it has
no l: variables, so that the variable is reported as undefined
instead.

Problem: b:match_words groups "{" with the if/for/while/switch keywords
and "}" with "break" which breaks % matching on braces
Solution: Drop the brace and bracket groups, matchit appends
'matchpairs' by itself (Matthias Bruns).
matchit counts every alternative in a group instead of pairing the
alternatives with each other. Listing `{` alongside the if, for,
while, switch, struct and class keywords therefore makes a line such
as `for (...) {` count as two openers, and listing `break` alongside
`}` lets a brace pair with a break statement. As a result % on the
opening brace of a function does not move at all, and % on
`switch (x) {` jumps to `break;` instead of the closing brace.
Braces and brackets do not need to be listed: matchit appends
'matchpairs' to b:match_words by itself. Drop them and leave the
preprocessor group unchanged.

Problem:
- Dot-repeat of a Visual selection prepared by a `<Cmd>` mapping,
results in E1255 and leaves Visual mode active.
- Visual-mode capture is implemented as a second, parallel "capture
engine": it re-composes a CmdSpec from cmdarg_T per key and decides
replayability from its own table of "void" key classes.
Solution:
- Model nested `normal_execute()` as a `CmdFrame` stack,
instead of a single module-scoped `stage`.
- Capture `<Cmd>` ":norm …" commands as subatoms from its nested frames.
- Produce every command exactly once; atom_push_raw() routes the atom to
the Visual composite while a selection is open, like it already does
for mapping composites.
- `v/pat<CR>d` is now repeatable and cascades.
Problem: The hit-enter prompt fires whenever a message scrolls the screen.
When this happens while a mapping is being processed, it consumes
the mapping's next key, causing unexpected behavior for users.
Solution: Similar to what 9.1.1969 did for stuffed characters, skip the
hit-enter prompt when there are still keys pending from a mapping
in the typeahead buffer.

Problem:
There is no unified notion of a "user action".
Vim processes input by one-char-at-a-time, and mostly throws away any
hints it might gather about the user's action, with one exception: it
stores the last _edit_ action (the "redo buffer", encoded as
unstructured `["x][v][count]body` bytes).
Plugins can only observe individual keys (vim.on_key) and high-level
effects (TextChanged, CursorMoved).
Solution:
- Users can subscribe to `CmdAtom` events to handle any user action.
- Event is deferred; handlers cannot cancel or interfere with user
actions.
- Capture `CmdSpec` from the normal/insert/visual subsystems.
- typeahead/readahead stay unstructured (`buffheader_T`): they are key
streams, not commands.
- the redo/record buffers become `StringBuilder`: fewer
allocations/copies.
- Repurpose the input/redo engine to accept `CmdSpec` objects.
"atom": one repeatable unit of user input, as a resolved (post-mapping)
keysequence plus structured fields. Only user actions, not `:normal`,
API calls, or non-"t" `feedkeys`.
BREAKING: dot-repeat of an Insert session, replays the entire session
including cursor-moves (:help ins-repeat).
BREAKING: dot-repeat of a Visual operation, replays the selection
instead of operating on a fixed-size region.
Problem: transstr() has comments that do not add anything to what the

Problem: sort() with "n", "N" or "f" converts an item to its number on
every comparison. For "n" that is a tv2string() plus strtod()
per comparison, so sorting a list of numbers turns each number
into a string and back O(n log n) times, dwarfing the sort.
Solution: Compute the numeric key of each item once, before the sort,
and compare the stored key (Samuel Schlesinger). Only the
builtin numeric compare modes are affected; uniq(), which
passes a bare list item to the compare function, and the
string and user-function paths are unchanged.
Sorting a list of 100000 numbers (min of 3, macOS arm64):
- sort(l, 'n'): 0.205s -> 0.017s
- sort(l, 'N'): 0.017s -> 0.010s
- sort(l, 'f'): 0.014s -> 0.010s
The result is identical, including that a string is still treated as 0
in "n" mode and that "N" keeps full 64-bit precision.
Add Test_sort_numeric_precomputed(): a large shuffled list sorted with
"n", mixed integers and floats, int64 values beyond the exact range of
a double for "N", and uniq() over the non-precomputed path.

Problem: Reading an undo file resolves every stored sequence number
with a linear scan over all headers, making loading
quadratic in the number of undo states.
Solution: Sort uhp_table on uh_seq once and resolve each reference
with a binary search; the duplicate uh_seq check becomes a
single pass over the sorted table (Samuel Schlesinger).
At the default 'undolevels' of 1000 the quadratic cost is not
measurable; it takes 'undolevels' in the tens of thousands to matter.
Loading an undo file with 20000 states and 50 alternate branches with
:rundo goes from 1.49s to 0.11s (min of 3, macOS arm64), with the
same undotree().
Also make old_idx/new_idx/cur_idx and the loop index "i" long instead
of short/int: they index uhp_table, whose length num_head is a long
read from the file. A short index truncated above 32767 headers,
making the restored b_u_oldhead/b_u_newhead/b_u_curhead pointers
wrong in exactly the many-headers case this change is about.
Add tests: a round-trip test with alternate branches that compares
the entries of the tree and the text at every sequence number, a
corruption test with a duplicated uh_seq, and a test for reading an
undo file with zero headers, which is written when only the line for
the "U" command is saved.

Problem:
- buf-local CWD scope is lower priority than :lcd, which is weird.
```
win > buf > tab > global
```
- No way to clear current CWD at a given scope.
Solution:
- Rerrange scope precedence to:
```
buf > win > tab > global
```
- Introduce "bang" variants (`:bcd!`/`:lcd!`/`:tcd!`) which clears the
local CWD for the given scope.
Problem:
- Explicit `:bcd` (etc.) persists from `nvim_buf_call()` but not from an
autocmd handler targeting a hidden buf (`LspAttach`, `TermRequest`, …),
which needs a `vim.schedule()` workaround.
- `vim._with()` is supposed to work as a "sandbox", discarding
side-effects, but it leaks CWD changes: `:lcd` from a `win` context,
any chdir from a visible-buffer context.
Solution:
- Explicit :cd/:tcd/:bcd during a temp context persists by default.
- "Ambient" directory changes ('autochdir', existing win-local CWD,
etc.) are still undone, as before.
- Add `kCtxKeepDirs`: snapshot/restore the target's full CWD state
(w/b/tp-local, global, cwd). Used by `vim._with()` and `'inccommand'`,
which must not leak state.
Problem: After :diffget into an empty buffer, undo does not restore the

Problem: "zb" scrolls incorrectly with cursor just above fold.
Solution: Handle boff.lnum being set to the last line of a fold
(zeertzjq).
With the cursor just above fold, botline_forw() moves boff.lnum to the
last line of the fold, but curwin->w_botline is at the first line of the
fold, so the boff.lnum == curwin->w_botline condition never holds.
Instead, check that boff.lnum has just moved to or past w_botline by
comparing its previous value with w_botline.
Also make a similar change to the loff.lnum check above for symmetry.
That one doesn't change behavior, as topline_back() sets loff.lnum to
the first line of a fold.
