/* 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] {| table |} 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.

/* 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 book ever, assumedBold and assumedItalic are saved on the stack and reset to          undefined (essentially, false) when recursing into a new block. */
