/**
 * 
 * Span plugin to change `` `text` `` to `<literal>text</literal>`.
 * 
 * Backtick quotes are used for `<code></code>` spans.
 * 
 * You can use multiple backticks as the delimiters if you want to
 * include literal backticks in the code span. So, this input ...
 * 
 *     Just type ``foo `bar` baz`` at the prompt.
 * 
 * ... will translate to ...
 * 
 *     <para>Just type <literal>foo `bar` baz</literal> at the prompt.</para>
 * 
 * There's no arbitrary limit to the number of backticks you
 * can use as delimters. If you need three consecutive backticks
 * in your code, use four for delimiters, etc.
 * 
 * You can use spaces to get literal backticks at the edges ...
 * 
 *     type `` `bar` ``
 * 
 * ... which turns into ...
 * 
 *     type <literal>`bar`</literal>
