Problem: The has() function is slow because it performs a linear scan
of the feature list for every call.
Solution: Move common runtime checks and the patch-version parser to the
beginning of the f_has() function (Yasuhiro Matsumoto).

Problem: "leadtab" behavior inconsistent on line with only TABs
(after 9.2.0088).
Solution: Don't consider those as leading TABs. Also add more tests for
existing behavior of "lead" and "leadmultispace" (zeertzjq).
closes: vim/vim#195494b30e40a1f
Problem: cannot display tabs for indentation
Solution: Add the "leadtab" value to the 'listchars' option to
distinguish between tabs used for indentation and tabs used
for alignment (HarshK97).

Problem: If Nvim server fails to --listen and prints error before the
TUI enters alternate screen, the error isn't visible.
Solution: Forward server stderr using client side stderr handler instead
of having the server inherit client stderr file descriptor.
This does mean that `stderr_isatty` will be `false` in the server, but
that value doesn't matter in embedded mode.
Always pass `stdin_fd` to embedded server to avoid a hang when reading
from stdin when it's a TTY (not sure why one wants to do that, perhaps
by mistake), because if `stdin_fd` isn't passed, the server will try to
use stderr as stdin.
Example test failure on CI:
FAILED test/functional/terminal/tui_spec.lua @ 41: TUI exit status 1 and error message with server --listen error #34365
test/functional/terminal\tui_spec.lua:55: Failed to match any screen lines.

Problem: When z= fails due to no word being found, 'spelllang' being

fix: allocate hidden console for detached server
Starting the server with UV_PROCESS_DETACHED results in DETACHED_PROCESS, leaving the child without a console. Without a console:
CONIN$ / CONOUT$ cannot resolve, causing channel_from_stdio to fail.
ConPTY cannot attach, breaking :terminal.
This patch allocates a hidden console via AllocConsole() when the server has none, restoring working stdio and enabling ConPTY.
Also updates os_set_cloexec to clear HANDLE_FLAG_INHERIT on the RPC pipe
handles, matching the Unix F_DUPFD_CLOEXEC behavior.
Problem: closing a minimal float saves its style-imposed options into
buffer's wininfo, which get picked up by normal windows on :bnext.
Solution: don't save window options to wininfo for style=minimal windows.
Problem:
When cross-compiling, `$<TARGET_FILE:nlua0>` resolves to the target
binary, which cannot run on the host machine during the build process.
Solution:
Allow passing a host native nlua0 binary via
`-DNLUA0_HOST_PRG=/path/to/nlua0` when cross-compiling, so code
generation can run correctly on the host.
Problem: memline: a crafted swap files with bogus pe_page_count/pe_bnum
values could cause a multi-GB allocation via mf_get(), and
invalid pe_old_lnum/pe_line_count values could cause a SEGV
when passed to readfile() (ehdgks0627, un3xploitable)
Solution: Add bounds checks on pe_page_count and pe_bnum against
mf_blocknr_max before descending into the block tree, and
validate pe_old_lnum >= 1 and pe_line_count > 0 before calling
readfile().

Problem: A stack-buffer-overflow occurs when rendering a statusline
with a multi-byte fill character on a very wide terminal.
The size check in build_stl_str_hl() uses the cell width
rather than the byte length, allowing the subsequent fill
loop to write beyond the 4096-byte MAXPATHL buffer
(ehdgks0627, un3xploitable).
Solution: Update the size check to account for the byte length of
the fill character (using MB_CHAR2LEN).

Problem: newline escape wrong in ex mode (Konrad Schwarz)
Solution: partly revert patch 7.3.014, remove backslash in front of a
newline when not in prompt mode in ex line mode
(Mohamed Akram)
This fixes newline escaping to allow passing multiple commands to
":global", multiple lines to shell commands, and ending lines in append
mode with backslashes. This should fix a POSIX/(traditional) VI
incompatiblity.
This reverts a previous incorrect attempt at patch v7.3.014 to fix
append mode which removed half of trailing backslashes which lead to,
eg. the following two commands being parsed as having a different number
of backslashes:
```
!echo foo\\\
```
```
!echo foo\\ \
```

Problem:
libvterm doesn't support parsing the dim and overline attributes, so when a program running in the embedded terminal emits one of these escape codes, we ignore it and don't surface it to the outer terminal.
Solution: tweak libvterm to add support for both attributes.
This makes little difference in practice except for extremely unlikely
ambiguities. But it looks nicer in compiler errors and stacktraces where
you see the fully expanded names
Problem:
Automatic background detection sets the background option too late,
which loads colorschemes twice and causes problems when the user's
terminal background doesn't match the default (#32109, #36211, #36416).
Solution:
Use a DA1 query to determine whether the TTY supports OSC 11. Wait for
background detection and setting to complete before processing user
config.
Note: To preserve the existing behavior as much as possible, this triggers
OptionSet manually on VimEnter (since it won't trigger automatically if
we set bg during startup). However, I'm unsure if this behavior is
truly desired given that the documentation says OptionSet is triggered
"After setting an option (except during |startup|)."
Also fixes flickering issue #28667. To check for flickering:
nvim --clean --cmd "set termguicolors" --cmd "echo \"foo\"" --cmd "sleep 10"
On master, this gives me a black screen for 10 seconds, but on this
branch, the background is dark or light depending on the terminal
background (since the option is now set during startup rather than after
VimEnter).
Problem: When nvim is started with "-s -" (read from stdin), ":restart"
drops the "-" argument but keeps "-s", leaving an orphaned "-s" in the
restarted server's argv, causing a crash.
Solution: Drop "-s" and its scriptfile argument when copying v:argv for
the restarted server. Like "-- [files…]", the scriptfile is a one-shot
startup input that should not be replayed on restart
Problem: Inefficient use of list_append_string()
Solution: Pass string length to list_append_string() where it is known
(John Marriott).

Problem: Leading message newlines (not emitted with ext_messages since
4260f73) were responsible for resetting the redirection message
column (while the newline itself is later pruned...).
Solution: Ensure the redirection column is reset at the start of a message.
(Instead of re-adjusting all the newline callsites which can
themselves hopefully be pruned if ext_messages is enabled by
default.)
fix#37867
This bug happens when only one end is moved between different nodes,
but the other end is also moved but within the same node.
When this happens we need the correct previous position even for the
internal move. This code shall be refactored to make the intent clearer,
(and avoid some unnecessary processing) but this is a fix for the observable
bug.
Thanks to KevinGoodsell for providing a deterministic
reproduce using fuzzing techniques.

fixes#37586
when doing `packadd mypackage` up to two exact paths are added
to &rtp. Instead of recalculating runtime_search_path from scratch,
we can "just" splice these two paths in
This is simple in theory, but get complicated in practice as
"after" dirs do exist and need some wrangling.
Echasnovski did some benchmarking, to show that this reduces overhead
of a init.lua configuration style where separate `packadd!` calls are
used spread out during the config. In addition, "batched" addition
(either using "start" packages or packadd! a lot of opt packages at
once) does not regress.
A theoretical simplification could be to NEVER explicitly add "after"
dirs to &rtp, but implicitly add all existing "after" dirs in reverse
order when calculating the effective run time path. This might be tricky
to do without breaking 12 tpope plugins again tho.
We might also instead consider solutions where &rtp remains fully expanded but no longer is the main source of truth. But this is all post 0.12 work. This PR is an alright stopgap to make 0.12 fully support intended use cases of vim.pack.add() .
Problem:
- `:args` and `argv()` can change after startup.
- `v:arg` includes options/commands, not just files.
- Plugins (e.g. Oil) may rewrite directory args.
Solution:
- New read-only var `v:argf`: snapshot of file/dir args at startup.
- Unaffected by `:args` or plugins.
- Unlike `v:argv`, excludes options/commands.
- Paths are resolved to absolute paths when possible
Example:
nvim file1.txt dir1 file2.txt
:echo v:argf
" ['/home/user/project/file1.txt', '/home/user/project/dir1', '/home/user/project/file2.txt']
Problem: Newlines emitted with ext_messages intended to position
the message/prompt on the message grid.
Solution: Don't emit these newlines with ext_messages, followup to 4260f73e.

Problem: after #33036, an error from evaluating 'statusline' clears it and
doesn't draw the statusline. (causing glitchy redraws)
Solution: use the default value instead. If 'stl' is somehow ever empty, still
call redraw_custom_statusline to at least draw an empty statusline.
Ideally our default 'stl' shouldn't itself error too! :-)
Also adjust some prior screen:expect()s to avoid immediate success warnings.
Problem:
- Editing a 'readonly' file forces a 3-second delay.
- nvim_get_mode waits 3 secs with 'showmode' enabled or when there are error messages.
Solution:
Remove the delay for "ui2", by using `msg_delay`.
It is indeed possible that a signal may arrive during flush_stream()
(e.g. SIGCHLD from another child process), so poll() again on EINTR.
Fixes the following Coverity warning:

Problem:
TUI does not support several standard SGR text attributes:
- dim/faint (SGR 2)
- blink (SGR 5)
- conceal (SGR 8)
- overline (SGR 53)
This means that when a program running in the embedded terminal emits
one of these escape codes, we drop it and don't surface it to the
outer terminal.
Solution:
- Add support for those attributes.
- Also add corresponding flags to `nvim_set_hl` opts, so users can set
these attributes in highlight groups.
- refactor(highlight): widen `HlAttrFlags` from `int16_t` to `int32_t`
Widen the `rgb_ae_attr` and `cterm_ae_attr` fields in HlAttrs from
int16_t to int32_t to make room for new highlight attribute flags,
since there was only one spare bit left.
- The C flag is named HL_CONCEALED to avoid colliding with the
existing HL_CONCEAL in syntax.h (which is a syntax group flag, not
an SGR attribute).
- Also note that libvterm doesn't currently support the dim and overline
attributes, so e.g. `printf '\e[2mThis should be dim\n'` and `printf
'\e[53mThis should have an overline\n'` are still not rendered
correctly when run from the embedded terminal.

Problem: When 'autocomplete' fires before compl_leader is initialized,
the prefix filter is bypassed. This allows non-prefix matches
(e.g. from fuzzy omnifuncs) to be shown in the popup menu and
incorrectly preinserted.
Solution: In get_leader_for_startcol(), if compl_leader.string is NULL,
fall back to using compl_orig_text as a filter for matches
starting at or after the completion column (Hirohito Higashi).
When 'autocomplete' first fires, compl_leader is NULL because
ins_compl_start() has not set it yet. This caused the prefix filter in
ins_compl_build_pum(), find_next_completion_match() and
find_common_prefix() to be bypassed, allowing non-prefix fuzzy omnifunc
matches to appear in the PUM and be preinserted.
Extend get_leader_for_startcol() to fall back to compl_orig_text when
compl_leader.string is NULL: if the match's cpt source startcol is less
than compl_col the match includes pre-compl_col text, so return
&compl_leader (NULL string) to signal "pass through"; otherwise return
&compl_orig_text so callers filter by the original text. The compl_col
<= 0 guard is kept only for the prepend-text path to avoid it
interfering with the NULL-leader fallback when compl_col is zero.
With this change all callers of get_leader_for_startcol() automatically
receive the correct filter string without additional helpers.
Also update Test_autocomplete_trigger Test 9 to reflect the new
behavior: 'faberge' is no longer shown when completing 'foo' because
it does not start with the current prefix.
Add Test_autocomplete_preinsert_null_leader() to verify that only
prefix-matching candidates appear in the PUM and are preinserted.
