Problem: [security] use-after-free with wildmenu
Solution: properly clean up the wildmenu when exiting
Fix wildchar/wildmenu/pum memory corruption with special wildchar's
Currently, using `wildchar=<Esc>` or `wildchar=<C-\>` can lead to a
memory corruption if using wildmenu+pum, or wrong states if only using
wildmenu. This is due to the code only using one single place inside the
cmdline process loop to perform wild menu clean up (by checking
`end_wildmenu`) but there are other odd situations where the loop could
have exited and we need a post-loop clean up just to be sure. If the
clean up was not done you would have a stale popup menu referring to
invalid memory, or if not using popup menu, incorrect status line (if
`laststatus=0`).
For example, if you hit `<Esc>` two times when it's wildchar, there's a
hard-coded behavior to exit command-line as a failsafe for user, and if
you hit `<C-\><C-\><C-N>` it will also exit command-line, but the clean
up code would not have hit because of specialized `<C-\>` handling.
Fix Ctrl-E / Ctrl-Y to not cancel/accept wildmenu if they are also
used for 'wildchar'/'wildcharm'. Currently they don't behave properly,
and also have potentially memory unsafe behavior as the logic is
currently not accounting for this situation and try to do both.
(Previous patch that addressed this: vim/vim#11677)
Also, correctly document Escape key behavior (double-hit it to escape)
in wildchar docs as it's previously undocumented.
In addition, block known invalid chars to be set in `wildchar` option,
such as Ctrl-C and `<CR>`. This is just to make it clear to the user
they shouldn't be set, and is not required for this bug fix.

Problem: A few remaining cmdline completion issues with C-E/Y
Solution: Fix cmdline completion fuzzy/Ctrl-E/Ctrl-Y/options when not
used at the end
Fix cmdline completion fuzzy/Ctrl-E/Ctrl-Y/options when not used at the end
A few places in the cmdline completion code only works properly when the
user hits Tab (or 'wildchar') at the end of the cmdline, even though
it's supposed to work even in the middle of the line.
For fuzzy search, `:e ++ff`, and `:set hl=`, fix completion code to make
sure to use `xp_pattern_len` instead of assuming the entire `xp_pattern`
is the search pattern (since it contains texts after the cursor).
Fix Ctrl-E / Ctrl-Y to not jump to the end when canceling/accepting a
wildmenu completion. Also, make them work even when not using
`set wildoptions+=pum` as there is no drawback to doing so.

Problem: completion shows current word after completion restart
Solution: remove the word being completed after completion restart
The word being completed is shown in a completion list after completion
restart, because it isn't removed from the current buffer before
searching for matches.
Also adjust `Test_complete_add_onechar` to match the new behavior.

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: 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.

Using fnameescape() for the path argument of findfile() and finddir() is
wrong, as fnameescape() is intended to be used for parts of Ex commands,
not function arguments.
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'.

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.
Problem:
On Windows, "gf" fails on a filepath that has a line:column suffix.
Example:
E447: Can't find file "src/app/core/services/identity/identity.service.ts:64:23"
Solution:
- Remove ":" from 'isfname' on Windows. Colon is not a valid filename
character (except for the drive-letter).
- Handle drive letters specially in file_name_in_line().
Fixes#25160
This finalizes the long running refactor from the old TUI-focused grid
implementation where text-drawing cursor was not separated from the
visible cursor.
Still, the pattern of setting cursor position together with updating a
line was convenient. Introduce grid_line_cursor_goto() to still allow
this but now being explicit about it.
Only having batched drawing functions makes code involving drawing
a bit longer. But it is better to be explicit, and this highlights
cases where multiple small redraws can be grouped together. This was the
case for most of the changed places (messages, lastline, and :intro)
Problem: Scrolling non-current window using mouse is inconsistent
depending on 'scrollbind'/'scrolloff' and different from GUI
vertical scrollbar when 'cursorbind' is set.
Solution: Don't move cursor in non-current windows for 'cursorbind' if
cursor in the current window didn't move.
