* The SyntaxHighlighter plugin passes all its arguments through a C++

I did not use beautifier, because it used up more than 8M of memory on
my system and PHP killed it. I'm not sure whether this is a problem
with my integration, or with beautifier itself.
Fixes by Reini Urban:
support options: syntax, style, color.
