    /* 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.

       Supported 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 ---- 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).

       Newlines are sucked up into ending tokens (including comments, bare
       external links, lists, horizontal lines, signatures, entities, etc.) to
       avoid creating spans with nothing but newlines in them.

       Flags: g for global search, m for make ^ match the beginning of each line
       and $ the end of each line

        /* About assumedBold and assumedItalic:

           Highlighting bold or italic markup presents a special challenge
           because the actual MediaWiki parser uses multiple passes to determine
           which ticks represent start tags and which represent end tags.
           Because that would be too slow for us here, we instead keep track of
           what kinds of unclosed opening ticks have been encountered and use
           that to make a good guess as to whether the next ticks encountered
           are an opening tag or a closing tag.

           The major downsides to this method are that '''apostrophe italic''
           and ''italic apostrophe''' are not highlighted correctly, and bold
           and italic are both highlighted in the same color.

           To permit ''The best<ref>''Reference Title''</ref> book ever'',
           assumedBold and assumedItalic are saved on the stack and reset to
           undefined (essentially, false) when recursing into a new block. */
