Wikilink titles can't handle escaped characters

[digitalmoksha]

With normal links, you can escape characters within the link's text. For example

[one \] two](http://one.com)

gives

<p><a href="http://one.com">one ] two</a></p>

However this does not work for wikilinks

[[one \] two|http://one.com]]

gives

<p><a href="http://one.com" data-wikilink="true">one \] two</a></p>

This makes it impossible to have a wikilink title with a character such as ]

What we want is

<p><a href="http://one.com" data-wikilink="true">one ] two</a></p>
