Problem: Wrong cursor position when entering command line window
Solution: Add check_cursor() command to verify the cursor position
(Hirohito Higashi).
When opening the command-line window with CTRL-F after typing a command
that fills the screen width, the cursor was placed past the end of the
line. Add check_cursor() after setting State to MODE_NORMAL so the
cursor is adjusted to the last character.
Also fix the cmdwin prefix character (e.g. ':') being drawn on wrapped
continuation rows. Draw an empty space instead so that the text
alignment is preserved.

Problem: runtime(tar): but with dotted path
Solution: Do not strip everything after the first dot
(Aaron Burrow)
tar#Extract was getting the extensionless basename by
stripping away everything starting with the leftmost
dot. So if a directory had a dot or the file had an
'extra' dot then the code did the wrong thing. For
example, if it was given:
/tmp/foo.bar/baz.tar.gz
Then it would treat /tmp/foo as the extensionless
basename, but it actually should have grabbed:
/tmp/foo.bar/baz
This patch fixes the issue by instead looking at the
rightmost dot(s).
This bug was discovered by ChatGPT 5.4. I wrote the
patch and tested vim.

Problem: patch 9.2.0325: runtime(tar): bug in zstd handling
Solution: use correct --zstd argument, separated from other arguments,
rework testing framework (Aaron Burrow).
The tar.vim plugin allows vim to read and manipulate zstd archives,
but it had a bug that caused extraction attempts to fail.
Specifically, if the archive has a .tar.zst or .tzst extension, then
the code was generating invalid extraction commands that looked like
this:
tar --zstdpxf foo.tar.zst foo
When they should be like this:
tar --zstd -pxf foo.tar.zst foo
This patch changes the flag manipulation logic so that --zstd isn't
glued to pxf.
The labor for this change was divided between ChatGPT 5.4 and me.
ChatGPT 5.4 identified the issue (from a code scan?), and I wrote
the patch and tested vim.

the unix.vim file was probably accidentally ignored at some point.
An actual invokation of nvim-under-test would in practice look like
["/path/to/neovim/build/bin/nvim", "-u", "unix.vim", "-U", "NONE", "-i", "NONE", "--noplugin", "--headless", "-u", "NONE", "--cmd", "set shortmess-=F", "-S", "runtest.vim", "test_arabic.vim"]
but -u NONE cancels out the earlier -u unix.vim
By now, too many tests rely on specific behavior from "NONE", so copy in
the useful parts of unix.vim to the cmdline again. also, some tests
conflict with `directory=.` (or even `directory=Xtempswapdir`) so don't use that.
`-U NONE` is dead code in Nvim, remove it.
Problem: runtime(tar): some issues with lz4 support
Solution: Fix bugs (see below) (Aaron Burrow)
The tar plugin allows users to extract files from tar archives that are
compressed with lz4. But, tar#Extract() builds malformed extraction commands
for lz4-compressed tar archives. This commit fixes three issues in that code.
The first affects archives with a .tlz4 extension and the other two affect
archives with .tar.lz4 extension (but one of these is symmetric to the issue
that .tlz4 archives had).
(1) When trying to extract .tlz4 archives the command created by
tar#Extract looked like this:
tar -I lz4pxf foo.tlz4 foo
This isn't right. It should be something like this:
tar -I lz4 -pxf foo.tlz4 foo
This was happening because tar.plugin is just substituting on the
first - in "tar -pxf". This works fine if we just add a simple flag for
extraction (eg, z for .tgz), but for lz4 we need to add "-I lz4".
I don't believe that there is an obvious good way to fix this without
reworking the way the command is generated. Probably we should collect
the command and flags separately and the flags should be stored in a
set. Then put everything together into a string just before issuing it
as an extraction command. Unfortunately, this might break things for users
because they have access to tar_extractcmd.
This patch just makes the substitution a little bit more clever so that it
does the right thing when substituting on a string like "tar -pxf".
(2) .tar.lz4 extractions had the same issue, which my patch fixes in
the same way.
(3) .tar.lz4 extractions had another issue. There was a space missing
in the command generated by tar#Extract. This meant that commands
looked like this (notice the lack of space between the archive and output
file names):
tar -I lz4pxf foo.tar.lz4foo
This patch just puts a space where it should be.
Finally, I should note that ChatGPT 5.4 initially identified this issue
in the code and generated the test cases. I reviewed the test cases,
wrote the patch, and actually ran vim against the tests (both with and
without the patch).

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)

b_nwindows = 0 change for free_all_mem() was already ported.
Originally Nvim returned true when b_nwindows was decremented before the end was
reached (to better indicate the decrement). That's not needed anymore, so just
return true only at the end, like Vim. (retval isn't used anywhere now anyways)
Set textlock for dict watchers at the end of close_buffer() to prevent them from
switching windows, as that can leave a window with a NULL buffer. (possible
before this PR, but the new assert catches it; added a test)
Despite textlock, things still aren't ideal, as watchers may observe the buffer
as unloaded and hidden (b_nwindows was decremented), yet still in a window...
Likewise, for Nvim, wipe_qf_buffer()'s comment may not be entirely accurate;
autocmds are blocked, but on_detach callbacks (textlocked) and dict watchers may
still run. Might be problematic, but those aren't new issues.

Problem: if close_buffer() in set_curbuf() unloads curbuf, NULL pointer
accesses may occur from enter_buffer() calling
end_visual_mode(), as curbuf is already abandoned and possibly
unloaded. Also, selection registers may not contain the
selection with clipboard+=autoselect(plus).
Solution: Move close_buffer()'s end_visual_mode() call to buf_freeall(), after
any autocmds that may restart it, but just before freeing anything
(Sean Dewar)

Problem: In gvim on Windows, a certain problem can occur when the
WM_SETFOCUS event sent after an external command is not
processed immediately.
Solution: After posting WM_SETFOCUS, run the message loop to process it
as quickly as possible (Muraoka Taro).
The problem is that Test_normal11_showcmd may fail when running the
test_normal.vim test. Investigation revealed that the trigger was an
external command executed in the previous test,
Test_mouse_shape_after_failed_change, when two tests were executed
consecutively. In gvim on Windows, a WM_SETFOCUS event will be sent
when an external command finishes executing. This WM_SETFOCUS event is
not processed immediately, but rather by redraw, which is expected to
update showcmd. Because it is queued in typebuf at this time,
clear_showcmd(), which expects typebuf to be empty, cannot update
showcmd.
Also added a test that simulates the above problem.

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: Option handling for key:value suboptions is limited
Solution: Improve :set+=, :set-= and :set^= for options that use
"key:value" pairs (Hirohito Higashi)
For comma-separated options with P_COLON (e.g., diffopt, listchars,
fillchars), :set += -= ^= now processes each comma-separated item
individually instead of treating the whole value as a single string.
For :set += and :set ^=:
- A "key:value" item where the key already exists with a different value:
the old item is replaced.
- An exact duplicate item is left unchanged.
- A new item is appended (+=) or prepended (^=).
For :set -=:
- A "key:value" or "key:" item removes by key match regardless of value.
- A non-colon item removes by exact match.
This also handles multiple non-colon items (e.g., :set
diffopt-=filler,internal) by processing each item individually, making
the behavior order-independent.
Previously, :set += simply appended the value, causing duplicate keys to
accumulate.
