Problem: Custom ui2 window tracks 'fillchars' option to adjust to the
change of `msgsep` flag. However, 'fillchars' is `:h global-local`
window option. If it is set locally to the window, ui2 reacts to its
`msgsep` value and keeps using it afterwards even in other windows.
Solution: Use and react to only global value of 'fillchars'.

Problem:
With 'ruler' in the cmdline ('laststatus=0') and ext_messages (ui2), a
'rulerformat' "%m" does not update the "[+]" indicator after ":write",
until a cursor-move.
Analysis:
`redraw_buf_status_later()` only marks windows with a statusline or
winbar. The symptom is hidden by the legacy message grid because the
write message overwrites the cmdline, which redraws the ruler.
Solution:
Also mark the cmdline 'ruler', like `status_redraw_buf()`.

Problem:
When repeating search using a semicolon (e.g. `/pat1/;/pat2`), `pat`
advances past both the semicolon and the delimiter ('/' or '?'),
consuming 2 characters, but `patlen` was only decremented by 1.
Consequently, `patlen` in the subsequent search is 1 byte too long and
includes the trailing NUL byte, corrupting `msgbuf` and causing ui2's
search_count handler to fail with 'attempt to concatenate a nil value'.
Solution:
Decrement `patlen` by 2 when skipping ';' and delimiter. Also ensure
ui2 safely guards search_count messages when extracting the search stat.
Fixes #41929

vim-patch:9.2.1114: Visual selection is not highlighted at the cursor position
Problem: In a terminal the character under the cursor is normally not
shown as part of the visual selection.
Solution: Don't set "noinvcur" in win_line() (Shane Harper).
The problem did not occur in the GUI, only in a terminal.
The name "noinvcur" ("don't invert the cursor") was misleading: the
variable did not affect the cursor, but whether the character under the
cursor could be displayed as part of the visual selection.
The "noinvcur" handling may have been meant to help during a visual
selection when Visual is shown in reverse video and the terminal draws
the cursor by inverting the character under it, as otherwise the
character under the cursor would not look highlighted like the rest of
the selection. But Vim cannot know in general how a terminal draws the
cursor, and when either the cursor is not drawn by inverting the
character under it or Visual is not shown in reverse video, the handling
just left a character of the visual selection unhighlighted.
closes: vim/vim#21317

Problem:
expand_msg() derives its start row from the pager buffer even when the
target is the cmd or dialog buffer, so the copied lines are appended
instead of replacing, and the copied extmarks are placed at pager rows in
a smaller buffer: "Invalid 'end_col': out of range", thrown inside a UI
event handler.
Solution:
Offset only when appending to a visible pager, and read the line count
after msg_clear(), whose autocmds may write to the pager. Copy marks with
`strict = false`, since the rows and columns are recomputed for a
different buffer and should clamp rather than raise.

Problem:

Problem:
cmd_on_key() tests the key it was handed against the literal string
'<MouseMove>', but at that point "typed" still holds raw key bytes. Thus
the comparison never holds and the branch its own comment describes
is dead. Moving the mouse over an expanded cmdline collapses it.
Solution:
Translate the key once, up front, so every comparison in the function
sees the same form.

Problem:
The "spill" indicator that ui2 appends when messages overflow the
available height is drawn with whatever highlight the message tail
happens to have, so it is indistinguishable from the message text.
Solution:
Give the [+x] chunks an explicit `MoreMsg` highlight, and only fall back
to the message tail highlight for chunks that don't carry one of their
own.

Problem:
The ui2 dialog implements paging for the arrow keys, Home/End and the
page keys, but not for the mouse wheel. When `mouse` contains `"c"`,
turning the wheel does nothing at all.
Solution:
Handle <ScrollWheelUp>/<ScrollWheelDown>, scrolling by the `mousescroll`
`"ver"` amount.

Other (squashed) commits:
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:
Unreliable ui2 test:
FAILED …/ui/messages2_spec.lua @ 277: messages2 multiline messages and pager
…/ui/messages2_spec.lua:277: Row 1 did not match.
Expected:
...

...
Actual:

|*{9:vim.schedule callback: ...ork/neovim/neovim/runt [+7]}|
Solution:
ui2 is doing contortions to handle the old cmdwin behavior; stop doing
that, it's no longer necessary since b2bf7bcfb151.

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:
Mapped keys can produce on_key callbacks with an empty `typed` value.
so mapped motions such as `j -> gj` are not recognized as typed input

mapped motions to dismiss messages like directly typed motions.

Problem: wrong end_row when copying extmarks to the pager buffer when expanding

copied lines and extmark rows.

Problem:
`inputlist()` advertises "click with the mouse" purely because it
implements click selection, so under the default `'mouse'` of "nvi" it
offers a click that command-line mode never receives.
Solution:
Only offer the mouse when `'mouse'` covers command-line mode, the same
condition `:help inputlist()` already documents.

- Avoid shared state. Pass `focus` to set_pos()/expand_msg() instead of
a shared `pager_focus` flag: the flag is only cleared when set_pos()
actually enters the pager, so ":messages" from inside the pager left
it set.
- pager_shown(): the pager window is invalid after leaving it with "q".
- Reuse pager_shown() in expand_msg().

Problem: A message emitted while a previous expanded message is still
visible opens the pager and enters it, moving focus away from
the buffer window without an explicit request (#41061).
Solution: Only enter the pager when it was explicitly requested ("g<",
:messages, or entered from the expanded cmdline). An unfocused
pager is dismissed by the cmdline key handler, which stays armed
across the cmdline and no longer dismisses on non-typed keys
(#39221).

Problem:
With `laststatus=3`, a pager float shares the main grid's statusline
row. Setting a diagnostic fires `DiagnosticChanged`, whose handler calls
`nvim__redraw({ statusline = true })`.
Analysis:
Inside the autocmd, `curwin` is temporarily switched to the tiled window
showing that buffer, so `win_redr_status()` paints its statusline over
the pager's `[Pager]` statusline on the shared row. After the autocmd,
`curwin` is restored but the pager statusline is never repainted.
Solution:
Use `ctx_saved_curwin()` decide whether to draw the global statusline,
matching `win_redr_stl_expr()` and `update_screen()`. No behavior change
if no buffer-context switch is active.

Problem:
The magic globals `it`, `describe`, etc., are more trouble than they are
worth.
- Hooking into `after_each` requires `getfenv()` hacks.
- They confuse luals/emmylua, because the top-level `.luarc.json` isn't
merged with `test/.luarc.json` (apparently a luals limitation?)
- They totally defeat discoverability because the user just has to
"know" about the various magic symbols.
So they harm DX, which means they serve no purpose at all.
Solution:
- Expose the test API from `testutil`, so tests can call `t.it()`,
`t.describe()`, etc., in the conventional way.
- Drop `getfenv()` hacks.
- Drop the `setfenv()` injection in `load_chunk`.
- Drop `test/_meta.lua`.

Problem: a long message is cropped to keep the ruler visible. But when
the message is repeated, it can be written over the ruler, while the
repetition indicator "(1)" is still placed just before the ruler, which
ends up somewhere inside the message.
Solution: currently, long messages are only cropped when setting the
'last' virttext. Make sure this happens after a repeated long message.

Problem: when the search count is displayed, the showcmd virt_text is
set to 11 empty spaces to ensure a consistent distance between search
count and ruler, or screen edge in case of noruler. But when the search
count is removed to make place for a message, the empty dummy showcmd
remains and unnecessarily erases part of the message.
Solution: properly remove showcmd together with search count.

Problem: before ui2, the ruler in the last line had a one cell safety
margin on the right because writing in the last column of the last line
"scrolls the screen up on some terminals," according to code comments.
When the ruler is included in the statusline, it aligns on the left with
the normal ruler, but goes all the way to the screen edge on the right,
and is therefore one cell longer.
Since ui2 doesn't have that padding cell, they don't align anymore.
Also, in the future, when the C implementation of the ruler will be
replaced with a default expression that will be included in the default
statusline (currently `%-14.(%l,%c%V%) %P`), the width will naturally be
the same in both places, and the unit tests will need adapting anyway.
Solution: when ui2 is active, increase the ruler width by 1.
BREAKING CHANGE: the default ruler in ui2 is now 1 cell wider.

Problem:
cmdwin (the `:q` cmdline buffer) has various limitations which require
special-casing all over the codebase.
Besides complicating the code, it also breaks async plugins if they try
to create buffers/windows after some work is done, if the user happens
to open cmdwin at the wrong the moment:
Lua callback: …/guh.nvim/lua/guh/util.lua:531:
E11: Invalid in command-line window; <CR> executes, CTRL-C quits
stack traceback:
[C]: in function 'nvim_buf_delete'
…/guh.nvim/lua/guh/util.lua:531: in function <…/guh.nvim/lua/guh/util.lua:526>
Solution:
Just say no to "inception". Reimplement cmdwin as a normal buffer+window.
All of the cmdwin contortions (in both core, and innocent plugins) exist
literally only to support "inception": recursive
cmdwin-in-cmdline-things, like `<c-r>=`, `/`, search-during-substitute,
`:input()`, etc. So we just won't support that (though I have
a potential plan for that later, which I call "modal parking lot").
The benefit is that plugins, and core, no longer have to care about
cmdwin.
BONUS:
- mouse-drag on vertical separators works (it only worked for
horizontal/statusline before)
- inccommand-in-cmdwin now works correctly, for free (thus don't need
#40077).
POTENTIAL FOLLOWUPS
- Drop `CHECK_CMDWIN` ("E11: Invalid in command-line window"), allow chaos.
- Unify `BUFLOCK_OK` / `LOCK_OK` ?
DESIGN:
- Eliminate lots of C globals, `EX_CMDWIN`, etc.
- `text_locked()` no longer reports true for cmdwin.
- cmdwin = a normal window with 'winfixbuf', 'bufhidden=wipe',
'buftype=nofile'. Invariants come from those options rather than
special cases throughout the codebase.
- `nv_record` for q:/q//q? calls Lua
`nlua_call_vimfn("vim._core.cmdwin", …)`. No `K_CMDWIN`
/ cmdline-reader detour.
- `cedit_key` (`c_CTRL-F`) schedules a deferred event that calls
`vim._core.cmdwin.open(type, content, pos)` and returns `Ctrl_C` so
the in-flight cmdline cancels. Reader state is not serialized; instead
the captured `(type, line, col)` is replayed via
`nvim_feedkeys(type..line.."<CR>", "nt", …)` after user confirms.
- On confirm/cancel: `<CR>` / `<C-C>` calls into Lua which closes the
window and re-feeds the cmdline.
BREAKING CHANGES:
- Expression-register cmdline (`<C-R>=` from insert-mode) no longer
supports cmdwin. Same applies to `input()` / `inputlist()` (already
covered by `text_locked`).
- Usage of cmdwin in macros/mappings will probably break (assuming they
ever worked).

Problem:
- Configuring the height of one of the message targets to 1 is
recognized as 100% of 'lines'.
- Cmdline is expanded for message exceeding 'cmdheight' even if the
configured height is smaller than or equal to 'cmdheight'.
Solution:
- Recognize a height of 1 as absolute; a decimal number smaller than 1
is taken as a fraction of 'lines' (replace 1 with 0.999 for the old
behavior).
- Don't expand the cmdline if the configured height doesn't allow it.

Problem: - "bufwrite" message identifier is encoded in the message ID
of a "progress" kind message (since ff68fd6b); UI2 does not
allow routing by message ID.
- No documented way to set a default message target for all
but a few kinds (without copying all of |ui-messages| kinds
to cfg.msg.targets).
- A user adding a message route for the documented empty ""
kind can result in unexpected behavior.
- Showing duplicate message (x) indicator in msg and cmd
targets simultaneously is unsupported.
- Manually triggering CursorMoved autocommand to add matchparen
highlighting in the cmdline.
Solution: - Match cfg.msg.targets keys as Lua pattern to a message ID.
- Recognize "default" as key in cfg.msg.targets, drop the
undocumented cfg.msg.target field.
- Don't try to get configured target for "" message kind/trigger.
- Maintain msg indicator virtual text for the cmd and msg target.
- Add matchparen highlighting by directly calling the Lua module
(possible since b813c7e0).

Problem:
- Unable to "pin" a window to prevent closing without specifically
being targeted.
- :fclose closes hidden windows (even before visible windows).
Solution:
- Add 'winpinned' window-local option. When set, window is skipped by
:fclose and :only. Pin the ui2 cmdline window (which should always be
visible), so that it is not closed by :only/fclose.
- Skip over hidden (and pinned) windows with :fclose.

Problem: - Paging keys in the dialog window consume input when the user
may not expect it. The dismissable title hint intended to
mitigate that results in having to press Escape twice to
abandon the prompt.
- Mimicked "msgsep" float border is taking up unnecessary
space when window takes up the entire screen.
Solution: - Use (conventional, albeit less convenient) keys intended
for scrolling to page the dialog window:
<(Mousewheel/Page)Up/Down>, <Home/End>.
- Only set the float top border when separation is actually
necessary, i.e. window does not reach the first row.

Problem: 'showcmd' causes flickering when pressing "g<" to enter the
pager when the cmdline is expanded for messages.
Initial keypress for an incomplete mapping is not giving 'showcmd'
feedback while cmdline is expanded for messages (which is only
dismissed upon the vim.on_key callback after 'timeoutlen').
Solution: Delay dismissing expanded cmdline when vim.on_key() callback
receives "g".
Place 'showcmd' "last" virtual text during expanded cmdline.
