This change does the following to the M4 syntax script:
- In M4 there are no "strings" in the usual sense. Instead, M4 has
quotes, but the text inside a quoted region is rescanned just like
outside, and quotes can be nested.
- The old m4String region was misleading and removed. A new m4Quoted
region reflects proper quoting semantics.
- Removed a duplicate highlight rule.
- Fixed a typo in a highlight group name (m4builtin → m4Builtin).
- Added a reference link to the POSIX M4 specification.
- Removed outdated maintainer URL.

No support is provided or planned for language recognition
in code snippets of documentation comments. Requesting to
load arbitrary syntax plugins with the aid of the concerned
variable is therefore wasteful in general and erroneous when
paired languages ":syn-include" one another without taking
steps to manage circularity.

- The main syntax file: runtime/syntax/cangjie.vim
- The filetype detection rule in: runtime/filetype.vim
- The documentation update in: runtime/doc/syntax.txt
- Some menus

These are special names by convention, and giving them distinct
highlighting is a nice visual clue (using Identifier by default).
This group is named "pythonClassVar" to match the name used by
python-syntax. Some third-party color schemes are aware of this
name and customized their colors accordingly.

A file containing only async functions (`async def func()`) wouldn't
previously match the pythonSync pattern.
Also, this pattern only matches at the beginning of the line, so it
won't ever match method definitions (which are indented within class
scopes). Update the comment accordingly.

Problem: cannot easily trigger wildcard expansion
Solution: Introduce wildtrigger() function
(Girish Palya)
This PR introduces a new `wildtrigger()` function.
See `:h wildtrigger()`
`wildtrigger()` behaves like pressing the `wildchar,` but provides a
more refined and controlled completion experience:
- Suppresses beeps when no matches are found.
- Avoids displaying irrelevant completions (like full command lists)
when the prefix is insufficient or doesn't match.
- Skips completion if the typeahead buffer has pending input or if a
wildmenu is already active.
- Does not print "..." before completion.
This is an improvement on the `feedkeys()` based autocompletion script
given in vim/vim#16759.

Problem:
- Extmark breaks lesson 3.1 of vim-01-beginner.tutor because when users
delete the line and put it elsewhere, the extmark doesn't move to the
put location.
- This doesn't mean the extmark implementation is bad though (note that
thanks to extmark, for the first time, we can make lesson 2.6 really
interactive), it's just that the tutor format has never been made for
kinds of lessons like lesson 3.1, which is why all "expected" in that
lesson are -1, which also means that lesson is not interactive in the
first place. Also see lesson 2.1.3 in vim-02-beginner, where the mark
is just used to mark the first line of the exercise, which also prove
my point.
Solution:
- For a not-really-interactive lesson like lesson 3.1, just use legacy
syntax. I borrow the old vimtutor's `--->` to mark the exercises of
the lesson.
- Less redundant interactive marks also make the json files smaller and
more maintainable.
- Match Ex command modifiers and functions with the same name correctly.
E.g., :browse and browse().
- Match full :eval command.

This change:
* enforces that the alias starts with a letter
* allows the other words in an alias to be separated by either a space
or a hyphen, but not both or double separators
* allows only a letter after space, possibly followed by letters or
digits
* allows both letters and digits after a hyphen
Tested with:
a = '\N{Cyrillic Small Letter Zhe} is pronounced as zh in pleasure'
b = '\N{NO-BREAK SPACE} is needed here'
# ... other tests here
r = '\N{HENTAIGANA LETTER E-1} is a Japanese hiragana letter archaic ye'
s = '\N{CUNEIFORM SIGN NU11 TENU} is a correction alias'
t = '\N{RECYCLING SYMBOL FOR TYPE-1 PLASTICS} base shape is a triangle'
print(a)
print(b)
print(r)
print(s)
print(t)
The tests confirm the behavior and are selected from real Unicode
tables/aliases to check these combinations based on the specification.
