Problem: When 'termguicolors' is used on MS-Windows (VTP mode), sending

The leading ESC triggers a beep or 'visualbell' flash.

Problem: possible crash with winminheight=0
(Emilien Breton)
Solution: Use <= instead of < when checking reserved room in
frame_setheight() to correctly handle the zero-height
boundary case (Hirohito Higashi).
In frame_setheight(), when shrinking the current window and the only
other window has 'winfixheight' with 'winminheight'=0, room_reserved
was not cleared because the condition used '<' instead of '<='.
The freed rows were discarded, leaving fr_height sum less than
topframe fr_height. Subsequent resize operations then computed a
wrong room_cmdline that expanded topframe beyond the screen, causing
a crash.

Problem: When using 'diffopt=inline:word', lines were excessively
fragmented with punctuation creating separate highlight
blocks, making it harder to read the diffs.
Solution: Added 'diff_refine_inline_word_highlight()' to merge
adjacent diff blocks that are separated by small gaps of
non-word characters (up to 5 bytes by default) (HarshK97).
When using inline:word diff mode, adjacent changed words separated by
punctuation or whitespace are now merged into a single highlight block
if the gap between them contains fewer than 5 non-word characters.
This creates more readable diffs and closely matches GitHub's own diff
display.

When system() or systemlist() is called without :silent from a
statusline expression, autocommand, or timer callback, the terminal
is temporarily set to cooked mode, which re-enables ECHO on the tty.
If a terminal response (e.g. DECRPM for cursor blink mode) arrives
during this window, the tty driver echoes it to the screen, leaving
stray characters that require CTRL-L to remove.
This behavior was intentionally addressed in patch 7.4.427 by
skipping cooked mode when :silent is prepended. However, the
documentation only mentioned this for system() and did not cover
systemlist() at all. The guidance to use :silent in non-interactive
contexts (statusline, autocommands, timers) was also not explicit.

Problem: invalid pointer casting in string_convert() arguments
Solution: Use a temporary local int variable (James McCoy)
string_convert()/string_convert_ext() accept an "int *lenp" parameter,
however a few call sites were taking the address of a possibly larger
type (long, size_t) and casting it as an int * when calling these
functions.
On big-endian platforms, this passes the (likely) zeroed high bytes of
the known length through to string_convert(). This indicates it received
an empty string and returns an allocated empty string rather than
converting the input. This is exhibited by test failures like
From test_blob.vim:
Found errors in Test_blob2str_multi_byte_encodings():
command line..script src/testdir/runtest.vim[636]..function RunTheTest[63]..Test_blob2str_multi_byte_encodings line 2: Expected ['Hello'] but got ['']
command line..script src/testdir/runtest.vim[636]..function RunTheTest[63]..Test_blob2str_multi_byte_encodings line 3: Expected ['Hello'] but got ['']
command line..script srctestdir/runtest.vim[636]..function RunTheTest[63]..Test_blob2str_multi_byte_encodings line 6: Expected ['Hello'] but got ['']
Instead, use a temporary local int variable as the in/out variable for
string_convert() and assign the result back to the larger typed length
variable post-conversion.

Solution: Always highlight visual selections with Visual when not

When Vim is running with X11 support it chooses between the Visual and

believes it owns the X selection. According to :help hl-VisualNOS,
VisualNOS should only be used by the X11 GUI or when using the

VisualNOS when a clipboard provider was used, even when Vim was not
