/* Define context-specific regexes, one for every common token that ends the
current context.
An attempt has been made to search for the most common syntaxes first,
thus maximizing performance. Syntaxes that begin with the same character
are searched for at the same time.
Wiki syntaxes from most common to least common:
[[internal link]] [http:// named external link]
{{template}} {{{template parameter}}} {| table |}
<tag> <!-- comment -->
http:// bare external link
=Heading= * unordered list # ordered list : indent ; small heading pre ---- horizontal line
''italic'' '''bold'''
three tildes username four tildes signature five tildes timestamp
&entity;
The tag-matching regex follows the XML standard closely so that users
won't feel like they have to escape sequences that MediaWiki will never
consider to be tags.
Only entities for characters which need to be escaped or cannot be
unambiguously represented in a monospace font are highlighted, such as
Greek letters that strongly resemble Latin letters. Use of other entities
is discouraged as a matter of style. For the same reasons, numeric
entities should be in hexadecimal (giving character codes in decimal only
adds confusion).
Flags: g for global search, m for make ^ match the beginning of each line
and $ the end of each line
