   /* 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. */
