MZMcBride noticed the red border around '國' in
https://en.wikipedia.org/wiki/Swift_(programming_language)#Example_code
That particular case happens to be a Pygments bug, because multibyte characters
are valid variable names in Swift. But even in cases of legitimate syntax
errors, I don't think we want to show the red border. This behavior may be
useful in code editors, but it is not useful in a wiki environment, especially
given the longstanding habit of using an existing, mostly-compatible lexer to
highlight a language for which no specific lexer exists.
To fix this, override the style in pygments.wrapper.css, and swap the order in
which the two CSS files are concatenated, so that in general we have the
ability to override Pygments-generated CSS.

Before we started using the 'code' tag for inline code snippets,
<code><syntaxhighlight enclose=none ...>...</syntaxhighlight></code>
was a common pattern. Continue supporting it in existing content.
Follow-up to 04293baad9. My IRC comments
about this were seemingly forgotten, and the code I added in
5b7522a5fc to handle this problem
unceremoniously removed.

The 'direction' rules must not be applied to regular preformatted
text in MediaWiki core, only to syntax-highlighted programming
language code.
(Not reverting the part that removes 'monospace' rule, *that* is
superfluous.)
This reverts commit f834b719b9.

The styles in MediaWiki core for <pre> already cover this. And
for skins that want different styles, SyntaxHighlight should not
have been overriding it.

I'm not entirely sure that this will always behave correctly on RTL
wikis, but currently we never behave correctly on RTL wikis.

It was always "none" and not "span", this must've been an accidental change.
Also add a CSS tweak to better render the common pattern of
<code><syntaxhighlight enclose="none">...</syntaxhighlight></code>.

GeSHi is unmaintained, lacks support for many popular modern languages, and
suffers from deep architectural flaws, chief among them the inconsistent
tokenization of different languages, each of which requires a custom
stylesheet.
Pygments is a well-maintained alternative. It is, by my count, the most popular
syntax highlighting library around. It is BSD-licensed, actively maintained,
and is widely used in PHP projects.
To keep this easy to review, this change does not include update for l10n
files, and it does not delete the geshi/ directory. I will do those in a
separate patch.
The chief change between this and the previous implementation is that errors
result in the code block not being highlighted, as opposed to not being printed
at all, having been replaced by an angry red error message. I think that is the
right user experience. If you go to StackOverflow or GitHub and try to mark up
your code block as being written in some language that their highlighter
doesn't know about, you don't get an error message -- the code simply doesn't
get highlighted.
Because we don't recursively load dependencies for extensions, to test this,
you will need to create a composer.local.json in $IP and add:
{
"extra": {
"merge-plugin": {
"include": [
"extensions/SyntaxHighlight_GeSHi/composer.json"
]
}
}
}
Then run `composer update`.
