BREAKING CHANGE: This breaks the OptionSet autocommand, as the `v:` values associated with it (`v:option_new`, `v:option_old`, `v:option_oldlocal` and `v:option_oldglobal`) are now the same type as the option, instead of all option values being converted to strings.
Problem: gcc overflow-warning for f_resolve
Solution: use pointer p instead of pointer q[-1]
Suppress the following warning:
```
filepath.c: In function ‘f_resolve’:
filepath.c:2162:27: warning: writing 1 byte into a region of size 0 [-Wstringop-overflow=]
2162 | q[-1] = NUL;
```

A lot of code inside HAVE_WORKING_LIBINTL doesn't really depend on a
"working libintl". For instance ex_language is also used for ":lang collate"
and ":lang time".
Also ":lang C" should not fail just because translations aren't available (it
just means use the default text).

Unmotivated switcharoo of get_mess_env() logic. If available, get_locale_val(LC_MESSAGES) is the correct implementation.
Problem: Cannot accurately get mouse clicking position when clicking on
a TAB or with virtual text.
Solution: Add a "coladd" field to getmousepos() result.

Problem: `TextChangedI` can trigger on entering Insert mode if there
was previously a change not in Insert mode.
Solution: Make it trigger only when text is actually changed in Insert
mode.

Problem: no max callback recursion limit
Solution: bail out, if max call recursion for callback functions
has been reached.
This checks the 'maxfuncdepth' setting and throws E169 when a callback
function recursively calls itself.

runtime(doc): Improve command-line completion docs (vim/vim#13331)
* Improve command-line completion docs
Add more details about 'ignorecase' and its effect on cmdline
completion.
Make sure keys used in wildmenu are properly documented and linked in the
keys' documentation entries, and in `:h index` for proper
cross-referencing, as wildmenu popup is slightly different from
insert-mode popup menu.
* Fix docs typos

Problem: When clicking in the middle of a TAB, getmousepos() returns
the column of the next char instead of the TAB.
Solution: Break out of the loop when the vcol to find is inside current
char. Fix invalid memory access when calling virtcol2col() on
an empty line.

Problem:
The next command after `silent !{cmd}` or `silent lua print('str')`
prints an empty line before printing a message, because these commands
set `msg_didout = true` despite not printing any messages.
Solution:
Set `msg_didout = true` only if `msg_silent == 0`
Problem: Peeking and flushing output slows down execution.
Solution: Do not update the mode message when global_busy is set. Do not
flush when only peeking for a character. (Ken Takata)

PROBLEM:
Currently `:echoerr` prints multi-line strings in a single line
as `:echom` does (Note: `:echon` can print multi-line strings well).
This makes stacktrace printed via echoerr difficult to read.
Example code:
try
lua error("lua stacktrace")
catch
echoerr v:exception
endtry
Output:
Error detected while processing a.vim[5]..a.vim:
line 4:
Vim(lua):E5108: Error executing lua [string ":lua"]:1: lua stacktrace^@stack traceback:^@^I[C]: in function 'error'^@^I[string ":lua"]:1: in main chunk
SOLUTION:
Allow echoerr to print multiline messages (e.g., lua exceptions),
because this command is usually used to print stacktraces.
Output after the fix:
Error detected while processing a.vim[5]..a.vim:
line 4:
Vim(lua):E5108: Error executing lua [string ":lua"]:1: lua stacktrace
stack traceback:
[C]: in function 'error'
[string ":lua"]:1: in main chunk
Problem: complete_info() returns wrong index
Solution: Make order of 'info' in completion_info consistent
Start the iteration from the same point and follow the same direction as
done when assigning the completion numbers. This way we remove the
dependence on the completion direction and make the order of 'info'
consistent.

Problem: The style guide states that all switch statements that are not conditional on an enum must have a `default` case, but does not give any explicit guideline for switch statements that are conditional on enums. As a result, a `default` case is added in many enum switch statements, even when the switch statement is exhaustive. This is not ideal because it removes the ability to have compiler errors to easily detect unchanged switch statements when a new possible value for an enum is added.
Solution: Add explicit guidelines for switch statements that are conditional on an enum, clarifying that a `default` case is not necessary if the switch statement is exhaustive. Also refactor pre-existing code with unnecessary `default` cases.
Problem: cmdline-completion for comma-separated options wrong
Solution: Fix command-line expansions for options with filenames with
commas
Fix command-line expansions for options with filenames with commas
Cmdline expansion for option values that take a comma-separated list
of file names is currently not handling file names with commas as the
commas are not escaped. For such options, the commas in file names need
to be escaped (to differentiate from a comma that delimit the list
items). The escaped comma is unescaped in `copy_option_part()` during
option parsing.
Fix as follows:
- Cmdline completion for option values with comma-separated file/folder
names will not start a new match when seeing `\\,` and will instead
consider it as one value.
- File/folder regex matching will strip the `\\` when seeing `\\,` to
make sure it can match the correct files/folders.
- The expanded value will escape `,` with `\\,`, similar to how spaces
are escaped to make sure the option value is correct on the cmdline.
This fix also takes into account the fact that Win32 Vim handles file
name escaping differently. Typing '\,' for a file name results in it
being handled literally but in other platforms '\,' is interpreted as a
simple ',' and commas need to be escaped using '\\,' instead.
Also, make sure this new logic only applies to comma-separated options
like 'path'. Non-list options like 'set makeprg=<Tab>' and regular ex
commands like `:edit <Tab>` do not require escaping and will continue to
work.
Also fix up documentation to be clearer. The original docs are slightly
misleading in how it discusses triple slashes for 'tags'.

This adds the checks in https://neovim.io/doc/reports/clang/ when using
clang-tidy. The strategy is to enable all clang-analyzer checks, and
disable only the checks for the warnings that exist currently. This
allows us to eliminate each warning type without blocking ongoing work,
but also without adding bugs for already eliminated warnings.
The plan is to eventually eliminate https://neovim.io/doc/reports/clang/
by completely integrating it into the clang-tidy check.
Also add make and cmake targets `clang-analyzer` to run this check.

"VimEnter foo" was accepted as a valid event name for "VimEnter".
Events delimited with commas, eg. "VimEnter,BufRead", were also
accepted, even though only the first event was actually parsed.

long is 32 bits on windows, while it is 64 bits on other architectures.
This makes the type suboptimal for a codebase meant to be
cross-platform. Replace it with more appropriate integer types.
The 'arabicshape' feature of vim is a transformation of unicode text to
make arabic and some related scripts look better at display time. In
particular the content of a cell will be adjusted depending on the
(original) content of the cells just before and after it.
This is implemented by the arabic_shape() function in nvim. Before this
commit, shaping was invoked in four different contexts:
- when rendering buffer text in win_line()
- in line_putchar() for rendering virtual text
- as part of grid_line_puts, used by messages and statuslines and
similar
- as part of draw_cmdline() for drawing the cmdline
This replaces all these with a post-processing step in grid_put_linebuf(),
which has become the entry point for all text rendering after recent
refactors.
An aim of this is to make the handling of multibyte text yet simpler.
One of the main reasons multibyte chars needs to be "parsed" into
codepoint arrays of composing chars is so that these could be inspected
for the purpose of shaping. This can likely be vastly simplified in many
contexts where only the total length (in bytes) and width of composed
char is needed.
