Problem: BSU/ESU are output directly to the terminal
Solution: Route them through out_buf() and flush the output directly,
increase the OUT_SIZE terminal buffer (Yasuhiro Matsumoto)
Route synchronized-output control sequences through out_buf and flush
explicitly at protocol boundaries, instead of forcing BSU/ESU through
ui_write() directly.
Also increase the terminal output buffer from 2047 to 8191 bytes so
large redraws are emitted in fewer writes.
The important guarantee here is terminal-visible ordering: BSU must
reach the terminal before the batched redraw bytes, ESU must reach the
terminal after them, and FLUSH must emit ESU and BSU together, then
flush immediately.
Benchmark: PTY redraw workload with TERM=xterm-256color, long wrapped
lines, cursorline, listchars, horizontal scrolling, and repeated redraw!.

Problem: typeahead buffer overflow during mouse drag event
Solution: Change the guard from 5 to 10 to account for the worst case
(Yasuhiro Matsumoto).
The typeahead buffer guard in mch_inchar() only reserved 5 bytes per
iteration, but a mouse event writes up to 7 bytes (3 header + 4
coordinates) and a scroll event with modifiers writes up to 10 bytes
(3 modifier + 3 scroll + 4 coordinates). During fast mouse dragging,
3+ events could queue up and overflow the 20-byte buffer, corrupting
adjacent static variables and causing garbage bytes (including Ctrl-Z)
to be fed into the input stream, which triggered nv_suspend/ex_stop.

Problem: unnecessary restrictions for defining dictionary function
names
Solution: Allow defining dict function with bracket key that is not a
valid identifier (thinca)
In Vim script, "function obj.func()" and "function obj['func']()" both
define a dictionary function. However, the bracket form required the
key to match function naming rules (eval_isnamec), so
"function obj['foo-bar']()" failed with E475.
Assigning and calling already work: "let obj['foo-bar'] = obj.func"
and "call obj['foo-bar']()" are valid. Only the definition was
incorrectly restricted.
Skip the identifier check when the name comes from fd_newkey (i.e. the
key was given in bracket notation). Dictionary keys may be any string.

Problem: hlset() cannot handle attributes with spaces
Solution: Handle attributes with spaces by quoting those
(Yasuhiro Matsumoto).
hlset(hlget('Normal')) fails with E416 when a highlight attribute value
contains spaces (e.g. font name "Monospace 10"). hlg_add_or_update()
builds a string like "font=Monospace 10" and passes it to do_highlight(),
whose parser splits on whitespace and treats "10" as a separate key
without "=".
Fix by quoting values with single quotes (e.g. font='Monospace 10')
when the value contains spaces and the attribute is a key=value pair.
do_highlight() already supports single-quoted values.

Problem: invalid lnum when pasting text copied blockwise
(KillTheMule)
Solution: Subtract nr_lines from curwin->w_cursor.lnum when calling
changed_lines() in do_put() (Pierluigi Lenoci)
When doing a blockwise paste beyond the end of the buffer, new lines are
appended and nr_lines is incremented accordingly. However, the
changed_lines() call used curwin->w_cursor.lnum as the "lnume" argument
(the first line below the changed lines BEFORE the change), which is
incorrect because the cursor has already been moved past the newly
appended lines.
Fix by subtracting nr_lines from curwin->w_cursor.lnum, so that lnume
correctly reflects the state before the change, as documented in
changed_lines().
Add a listener test to verify the correct values are reported.

Problem: terminal: redraws are slow (Mao-Yining)
Solution: Disable redrawing in handle_movecursor()
(Yasuhiro Matsumoto)
handle_movecursor callback was calling update_cursor() with redraw=TRUE
on every cursor move inside vterm_input_write(). This triggered
gui_mch_flush() (GdiFlush + DWriteContext_Flush) and TextChangedT
autocmd for each cursor move. ConPTY output contains ~17 cursor moves
per 4KB chunk, each flush taking ~5ms, resulting in 80-110ms per chunk.
Fix by passing FALSE to update_cursor() in handle_movecursor since
write_to_term() already calls update_cursor() with proper redraw after
vterm_input_write() finishes.
Also set vterm_screen_set_damage_merge() to VTERM_DAMAGE_SCROLL so that
damage callbacks are buffered until vterm_screen_flush_damage() instead
of being emitted per cell.

Problem: close_buffer() callers incorrectly handle b_nwindows,
especially after nasty autocmds, allowing it to go
out-of-sync. May lead to buffers that can't be unloaded, or
buffers that are prematurely freed whilst displayed.
Solution: Modify close_buffer() and review its callers; let them
decrement b_nwindows if it didn't unload the buffer. Remove
some now unneeded workarounds like 8.2.2354, 9.1.0143,
9.1.0764, which didn't always work (Sean Dewar)
close_buffer() now doesn't decrement b_nwindows when not unloading buf, or when
buf isn't w_buffer after autocmds (they would've already decremented it).
Callers are now expected to decrement b_nwindows if w_buffer is not NULL after
close_buffer(), and when still intending to switch buffers or close win, for two
reasons:
- close_buffer() autocmds may have switched buffers. The new w_buffer's
b_nwindows would also need decrementing.
- After close_buffer(), callers may opt to not switch w_buffer or close win.
b_nwindows would need to be incremented again. (unless w_buffer is NULL from
being unloaded; callers are already forced to find a new buffer then)
These were the main causes of b_nwindows bugs, as these cases could not be
reliably detected, and went largely unhandled.
NOTE: if close_buffer() autocmds switch buffers, close_buffer() is not called
for that new buffer before decrementing b_nwindows. This may skip side-effects
like from 'bufhidden', but I think it's mostly harmless, and was already
happening in other places.
Let's see how this goes... Other details: (I have lots to say!)
It's OK to pass a win to close_buffer() that isn't showing buf (used by
set_curbuf()). In that case, we skip some side-effects and don't decrement
b_nwindows, but may still unload buf if hidden.
buf_freeall() now returns whether it freed anything. Removes some repeated
checks in close_buffer().
Preserve close_buffer()'s behaviour when called by win_free_popup() after its
popup was already removed from the window list. This made win_valid_any_tab()
return FALSE, so we skip things that originally checked it in that case.
Add "set_context" to close_buffer() to preserve do_ecmd()'s behaviour of only
setting b_last_cursor and/or calling buflist_setfpos() when not splitting
(see 7.2.041: https://groups.google.com/g/vim_dev/c/ZGgNvaylNzI/m/WHxjhnuxqB0J)
Without this, Test_marks_cmd() fails from its ' mark differing. Don't use
oldwin though; it's not always the window with the closed buf, especially
after BufLeave autocmds in do_ecmd(). Also, only set context if win is really
displaying buf.
Don't bail in do_ecmd() if buf was deleted but curwin->w_buffer is NULL; that
leaves curwin open to a NULL buffer! Use lastbuf instead, like set_curbuf().
I don't think it's possible for buf to be deleted by close_buffer() anyway, as
b_locked was set (which I can't see a way to bypass, unlike b_locked_split).
Maybe such checks can be removed, but I'd rather not risk that here.
Don't set curwin to previouswin in set_curbuf(); shouldn't be needed, otherwise
may lead to curbuf != curwin->w_buffer if autocmds switch to a window showing
buf, as that skips enter_buffer()? Was introduced back in 7.3.557 to avoid
cases where autocmds switch windows, possibly leaving previouswin with a NULL
buffer. Since 7.4.2312 and 7.4.2328, close_buffer() and buf_freeall() already
handles this. I've added an assert() as a sanity check anyway.
In free_all_mem(), set b_nwindows to 0 before close_buffer() so buffers can be
wiped if still in a window before win_free_all(). Needed as close_buffer() now
skips unloading buffers that aren't hidden if win is NULL. If it's possible for
free_all_mem()'s :tabonly! and :only! to not close all windows before freeing,
then this issue was also previously possible if b_nwindows > 1.

Problem: json_decode() accepted keywords case-insensitively, violating

Solution: Only allow lowercase keyword in json_decode(), reject lone

1. Fix surrogate pair range check (0xDFFF -> 0xDBFF) so only high

2. Use case-sensitive matching for JSON keywords (true, false, null,
