Problem:
Variables are often assigned multiple places in common patterns.
Solution:
Replace these common patterns with different patterns that reduce the
number of assignments.
Use `MAX` and `MIN`:
```c
if (x < y) {
x = y;
}
// -->
x = MAX(x, y);
```
```c
if (x > y) {
x = y;
}
// -->
x = MIN(x, y);
```
Use ternary:
```c
int a;
if (cond) {
a = b;
} els {
a = c;
}
// -->
int a = cond ? b : c;
```
Problem: signed number detection for CTRL-X/A can be improved
(Chris Patuzzo)
Solution: Add the new "blank" value for the 'nrformat' setting. This
will make Vim assume a signed number only if there is a blank
in front of the sign.

utf8proc already defines LATIN CAPITAL LETTER SHARP S (ẞ) to be the
uppercase variant of LATIN SMALL LETTER SHARP S (ß), so this special
workaround when using `gU` is no longer needed on the neovim side.
The latter was mostly relevant with the past char_u madness.
NOTE: STRCAT also functioned as a counterfeit "NOLINT" for clint
apparently. But NOLINT-ing every usecase is just the same as disabling
the check entirely.
Problem: Coverity complains about division by zero
Solution: Check explicitly for sw_val being zero
Shouldn't happen, since tabstop value should always be larger than zero.
So just add this as a safety measure.

Problem: Left shift is incorrect with vartabstop and shiftwidth=0
Solution: make tabstop_at() function aware of shift direction
(Gary Johnson)
The problem was that with 'vartabstop' set and 'shiftwidth' equal 0,
left shifts using << were shifting the line to the wrong column. The
tabstop to the right of the first character in the line was being used
as the shift amount instead of the tabstop to the left of that first
character.
The reason was that the tabstop_at() function always returned the value
of the tabstop to the right of the given column and was not accounting
for the direction of the shift.
The solution was to make tabstop_at() aware of the direction of the
shift and to choose the tabtop accordingly.
A test was added to check this behavior and make sure it doesn't
regress.
While at it, also fix a few indentation/alignment issues.

Problem: getregionpos() doesn't handle one char selection.
Solution: Handle startspaces differently when is_oneChar is set.
Also add a test for an exclusive charwise selection with
multibyte chars (zeertzjq)
closes: vim/vim#1482552a6f34887
Problem: getregionpos() wrong with blockwise mode and multibyte.
Solution: Use textcol and textlen instead of start_vcol and end_vcol.
Handle coladd properly (zeertzjq).
Also remove unnecessary buflist_findnr() in add_regionpos_range(), as
getregionpos() has already switched buffer.

Problem: ops.c code uses too many strlen() calls
Solution: Refactor code and remove more strlen() calls

Problem: Using xstrlcpy() when the exact length of the string to be
copied is known is not ideal because it requires adding 1 to
the length and an unnecessary strlen().
Solution: Add xmemcpyz() and use it in place of such xstrlcpy() calls.
Problem: Coverity reports dead code.
Solution: Remove the dead code. Also fix a mistake in ml_get_pos_len()
and update some comments (zeertzjq).
closes: vim/vim#141898c55d60658
Problem: More code can use ml_get_buf_len() instead of STRLEN().
Solution: Change more STRLEN() calls to ml_get_buf_len(). Also do not
set ml_line_textlen in ml_replace_len() if "has_props" is set,
because "len_arg" also includes the size of text properties in
that case. (zeertzjq)
closes: vim/vim#1418394b7c3233e
Problem: Text properties position wrong after shifting text.
Solution: Adjust the text properties when shifting a block of text.

A lot of functions in move.c only worked for curwin, alternatively
took a `wp` arg but still only work if that happens to be curwin.
Refactor those that are needed for update_topline(wp) to work
for any window.

Problem: using "C" and 've=all' set, doesn't include composing chars

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: i_CTRL-R- doesn't work for multibyte chars in Replace mode,

for u_save_cursor() correctly (@zeertzjq)
closes: vim/vim#13846424ec1f235
Problem: i_CTRL-R- no longer works in replace mode

is not supported in Replace mode for now

Remove `export` pramgas from defs headers as it causes IWYU to believe
that the definitions from the defs headers comes from main header, which
is not what we really want.
Problem: reg_executing() returns wrong result in :normal with range
when 'showcmd' is set (after 8.2.4705).

We already have an extensive suite of static analysis tools we use,
which causes a fair bit of redundancy as we get duplicate warnings. PVS
is also prone to give false warnings which creates a lot of work to
identify and disable.
