Tag folding poses a few difficulties. Many elements, e.g.
"blockquote", are always delimited by start and end tags;
end tags for some elements, e.g. "p", can be omitted in
certain contexts; void elements, e.g. "hr", have no end tag.
Although the rules for supporting omissible end tags are
ad-hoc and involved, they apply to elements in scope.
Assuming syntactical wellformedness, an end tag can be
associated with its nearest matching start tag discoverable
in scope and towards the beginning of a file, whereas all
unbalanced tags and inlined tags can be disregarded.
For example:
------------------------------------------------------------
<!DOCTYPE html>
<html lang="en"> <!-- >1 : 1 -->
<body> <!-- >2 : 2 -->
<p>Paragraph #1. <!-- = : 2 -->
<p> <!-- >3 : 3 -->
Paragraph #2. <!-- = : 3 -->
</p> <!-- <3 : 3 -->
<p>Paragraph #3.</p> <!-- = : 2 -->
</body> <!-- <2 : 2 -->
</html> <!-- <1 : 1 -->
------------------------------------------------------------
(HTML comments here, "<!-- ... -->", record two values for
each folded line that are separated by ":", a value obtained
from "&foldexpr" and a value obtained from "foldlevel()".)
Innermost foldedable tags will be flattened. For example:
------------------------------------------------------------
<!DOCTYPE html>
<html lang="en"> <!-- >1 : 1 -->
<body> <!-- >2 : 2 -->
<div class="block"> <!-- >3 : 3 -->
<pre><code> <!-- >4 : 4 -->
[CODE SNIPPET] <!-- = : 4 -->
</code></pre> <!-- <4 : 4 -->
</div> <!-- <3 : 3 -->
</body> <!-- <2 : 2 -->
</html> <!-- <1 : 1 -->
------------------------------------------------------------
No folding will be requested for the "<code>"-"</code>" tag
pair and reflected by "&foldexpr" because such a fold would
have claimed the same lines that the immediate fold of the
"<pre>"-"</pre>" tag already claims.
Run-on folded tags may confuse Vim. When a file such as:
------------------------------------------------------------
<!DOCTYPE html>
<html lang="en"> <!-- >1 : 1 -->
<body> <!-- >2 : 2 -->
<div class="block"> <!-- >3 : 3 -->
<pre> <!-- >4 : 4 -->
<code> <!-- >5 : 5 -->
[CODE SNIPPET #1] <!-- = : 5 -->
</code> <!-- <5 : 5 -->
</pre> <!-- <4 : 4 -->
</div> <!-- <3 : 3 -->
<!-- = : 3 -->
<div class="block"> <!-- >3 : 3 -->
<pre> <!-- >4 : 4 -->
<code> <!-- >5 : 5 -->
[CODE SNIPPET #2] <!-- = : 5 -->
</code> <!-- <5 : 5 -->
</pre> <!-- <4 : 4 -->
</div> <!-- <3 : 3 -->
</body> <!-- <2 : 2 -->
</html> <!-- <1 : 1 -->
------------------------------------------------------------
is reformatted as follows:
------------------------------------------------------------
<!DOCTYPE html>
<html lang="en"> <!-- >1 : 1 -->
<body> <!-- >2 : 2 -->
<div class="block"> <!-- >3 : 3 -->
<pre> <!-- >4 : 4 -->
<code> <!-- >5 : 5 -->
[CODE SNIPPET #1] <!-- = : 5 -->
</code> <!-- <5 : 5 -->
</pre> <!-- <4 : 4 -->
</div><div class="block"><pre><code> <!-- <3 : 3 -->
[CODE SNIPPET #2] <!-- = : 2 ? -->
</code> <!-- <5 : 2 ? -->
</pre> <!-- <4 : 2 ? -->
</div> <!-- <3 : 2 ? -->
</body> <!-- <2 : 2 -->
</html> <!-- <1 : 1 -->
------------------------------------------------------------
"&foldexpr" values will not be used as is for the lines
between (and including) "[CODE SNIPPET #2]" and "</div>".
(Cf. v9.1.0002.)
Having syntax highlighting in effect, tag folding using the
"fold-expr" method can be enabled with:
------------------------------------------------------------
let g:html_expr_folding = 1
------------------------------------------------------------
By default, tag folding will be redone from scratch after
each occurrence of a TextChanged or an InsertLeave event.
Such frequency may not be desired, especially for large
files, and this recomputation can be disabled with:
------------------------------------------------------------
let g:html_expr_folding_without_recomputation = 1
doautocmd FileType
------------------------------------------------------------
To force another recomputation, do:
------------------------------------------------------------
unlet! b:foldsmap
normal zx
------------------------------------------------------------

On man-db systems, complete with actual man sections and pages, instead
of shell commands.
I tried to come up with a portable solution for multiple man
implementations in https://github.com/vim/vim/discussions/16794 but I
think the differences between implementations were too large to do that
without overly complicated code. So instead, I implemented it for man-db
(which I think is common on Linux) and hopefully left it easier for
other people to implement it on other systems in the future if they want
to.

(see `runtime/syntax/lua.vim`)
- `includeexpr` doesn't work with module in `init.lua`
Solution:
- Update documentation
- Assign value to option `&include`
- Add function `LuaInclude` and assign it to `l:&includeexpr`

The new native commenting functionality is currently not used when
editing mail. One could reasonably expect it to change the "quote" state
of any given line in the mail (i.e. the preceding ">"), which would be
very handy and feel natural when editing mail. Especially since the
current file already uses "setlocal comments+=n:>".
Solution: Add commentstring to `> %s` to be used in files of type mail.

Complement "g:java_ignore_javadoc" with "g:java_ignore_html"
and "g:java_ignore_markdown" to allow selectively disabling
the recognition of HTML and CommonMark respectively.
(Note that this is not a preview feature.)
======================== LIMITATION ========================
According to the syntactical details of JEP 467:
> Any leading whitespace and the three initial / characters
> are removed from each line.
>
> The lines are shifted left, by removing leading whitespace
> characters, until the non-blank line with the least
> leading whitespace has no remaining leading whitespace.
>
> Additional leading whitespace and any trailing whitespace
> in each line is preserved, because it may be significant.
the following example:
------------------------------------------------------------
/// A summary sentence.
/// A list:
/// - Item A.
/// - Item B.
///
/// Some code span, starting here `
/// 1 + 2 ` and ending at the previous \`.
------------------------------------------------------------
should be interpreted as if it were written thus:
------------------------------------------------------------
///A summary sentence.
/// A list:
/// - Item A.
/// - Item B.
///
/// Some code span, starting here `
/// 1 + 2 ` and ending at the previous \`.
------------------------------------------------------------
Since automatic line rewriting will not be pursued, parts of
such comments having significant whitespace may be ‘wrongly’
highlighted. For convenience, a &fex function is defined to
‘correct’ it: g:javaformat#RemoveCommonMarkdownWhitespace()
(:help ft-java-plugin).

This is a followup to 816fbcc262 (patch
9.0.1833: [security] runtime file fixes)
It basically disables that external commands are run on loading of the
filetype plugin, **unless** the user has set the `g:plugin_exec = 1`
global variable in their configuration or for a specific filetype the
variable g:<filetype>_exec=1.
There are a few more plugins, that may execute system commands like
debchangelog, gitcommit, sh, racket, zsh, ps1 but those do at least
do not run those commands by default during loading of the filetype plugin
(there the command is mostly run as convenience for auto-completion or
to provide documentation lookup).
