   *   *  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:
   *
   *         <p>Just type <code>foo `bar` baz</code> at the prompt.</p>
   *
   *    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` `` ...
   *
   *       Turns to:
   *
   *         ... type <code>`bar`</code> ...
