Problem: The matchparen plugin is slow on a long line.
Solution: Don't use a regexp to get char at and before cursor.
(zeertzjq)
Example:
```vim
call setline(1, repeat(' foobar', 100000))
runtime plugin/matchparen.vim
normal! $hhhhhhhh
```

Problem: [security] use-after-free in tagstack_clear_entry
(Suyue Guo )
Solution: Instead of manually calling vim_free() on each of the tagstack
entries, let's use tagstack_clear_entry(), which will
also free the stack, but using the VIM_CLEAR macro,
which prevents a use-after-free by setting those pointers
to NULL
This addresses CVE-2024-41957

Problem: Unable to leave long line with 'smoothscroll' and 'scrolloff'.
Corrupted screen near the end of a long line with 'scrolloff'.
(Ernie Rael, after 9.1.0280)
Solution: Only correct cursor in case scroll_cursor_bot() was not itself
called to make the cursor visible. Avoid adjusting for
'scrolloff' beyond the text line height (Luuk van Baal)

Problem: No test that completing a partial mapping clears 'showcmd'.
Solution: Complete partial mappings in Test_showcmd_part_map() instead
of using :echo. Adjust some comments (zeertzjq).
closes: vim/vim#14580094c4390bd
Problem: 'showcmd' is wrong for partial mapping with multibyte char,
and isn't very readable with modifyOtherKeys.
Solution: Decode multibyte char and merge modifiers into the char.
(zeertzjq)
This improves the following situations:
- Multibyte chars whose individual bytes are considered unprintable are
now shown properly in 'showcmd' area.
- Ctrl-W with modifyOtherKeys now shows ^W in 'showcmd' area.
The following situation may still need improvement:
- If the char is a special key or has modifiers that cannot be merged
into it, internal keycodes are shown in 'showcmd' area like before.
This applies to keys typed in Normal mode commands as well, and it's
hard to decide how to make it more readable due to the limited space
taken by 'showcmd', so I'll leave it for later.

Problem: "zb" does not reveal filler lines at the start of a buffer.
Scrolled cursor position with 'smoothscroll' is unpredictable,
and may reset skipcol later if it is not visible (after v9.1.258)
Solution: Replace confusing for loop that reaches final control value too
early with while loop. Set "w_curswant" accordingly so cursor
will be placed in visible part of topline.

Problem: Page-wise scrolling with Ctrl-D/Ctrl-U implements
it's own logic to change the topline and cursor.
More logic than necessary for scrolling with Ctrl-F/Ctrl-B
was removed in patch 9.1.0211.
Solution: Re-use the logic from Ctrl-E/Ctrl-Y/Ctrl-F/Ctrl-B while
staying backward compatible as much as possible.

This is the first installment of a multi-PR series significantly
refactoring how highlights are being specified.
The end goal is to have a base set of 20 ish most common highlights,
and then specific files only need to add more groups to that as needed.
As a complicating factor, we also want to migrate to the new default
color scheme eventually. But by sharing a base set, that future PR
will hopefully be a lot smaller since a lot of tests will be migrated
just simply by updating the base set in place.
As a first step, fix the anti-pattern than Screen defaults to ignoring
highlights. Highlights are integral part of the screen state, not
something "extra" which we only test "sometimes". For now, we still
allow opt-out via the intentionally ugly
screen._default_attr_ids = nil
The end goal is to get rid of all of these eventually (which will be
easier as part of the color scheme migration)
Problem: Cursor pos wrong when double-width chars are concealed.
Solution: Advance one more virtual column for a double-width char.

Problem: 'cursorline' and 'wincolor' highlight missing with concealed and
wrapped lines.
Solution: Apply 'cursorline' and 'wincolor' highlight to boguscols.
(zeertzjq)
Since 'cursorline' and 'wincolor' highlight apply after the end of the
line, it is more consistent to have them also apply to boguscols.
Assigning MAXCOL to values in ScreenCols[] make mouse click behave the
same with 'cursorline' and 'nocursorline', but such behavior may be
incorrect, as it puts the cursor on the next screen line. That may be
fixed in a future PR.

Problem: upper-case of ß should be U+1E9E (CAPITAL LETTER SHARP S)
(fenuks)
Solution: Make gU, ~ and g~ convert the U+00DF LATIN SMALL LETTER SHARP S (ß)
to U+1E9E LATIN CAPITAL LETTER SHARP S (ẞ), update tests
(glepnir)
This is part of Unicode 5.1.0 from April 2008, so should be fairly safe
to use now and since 2017 is part of the German standard orthography,
according to Wikipedia:
https://en.wikipedia.org/wiki/Capital_%E1%BA%9E#cite_note-auto-12
There is however one exception: UnicodeData.txt for U+00DF
LATIN SMALL LETTER SHARP S does NOT define U+1E9E LATIN CAPITAL LETTER
SHARP S as its upper case version. Therefore, toupper() won't be able
to convert from lower sharp s to upper case sharp s (the other way
around however works, since U+00DF is considered the lower case
character of U+1E9E and therefore tolower() works correctly for the
upper case version).

Problem: [security]: stack-buffer-overflow in option callback functions
Solution: pass size of errbuf down the call stack, use snprintf()
instead of sprintf()
We pass the error buffer down to the option callback functions, but in
some parts of the code, we simply use sprintf(buf) to write into the error
buffer, which can overflow.
So let's pass down the length of the error buffer and use sprintf(buf, size)
instead.

Problem: [security]: use-after-free in win-enter
Solution: validate window pointer before calling win_enter()
win_goto() may stop visual mode, if it is active. However, this may in
turn trigger the ModeChanged autocommand, which could potentially free
the wp pointer which was valid before now became stale and points to now
freed memory.
So before calling win_enter(), let's verify one more time, that the
wp pointer still points to a valid window structure.

Problem: buffer-overflow in trunc_string()
Solution: Add NULL at end of buffer
Currently trunc_string() assumes that when the string is too long,
buf[e-1] will always be writeable. But that assumption may not always be
true. The condition currently looks like this
else if (e + 3 < buflen)
[...]
else
{
// can't fit in the "...", just truncate it
buf[e - 1] = NUL;
}
but this means, we may run into the last else clause with e still being
larger than buflen. So a buffer overflow occurs.
So instead of using `buf[e - 1]`, let's just always
truncate at `buf[buflen - 1]` which should always be writable.
