code blocks - automatically reset indent & beginning/ending lines

[jyoungblood]

I don't like the way we have to format the code blocks right now, would love to automatically reset the indentation and ignore the first and last lines if they're blank.

So instead of this

      <pre><code class="language-php">function literally($string){
  return $string;
}</code></pre>

We could write this

      <pre><code class="language-php">
         function literally($string){
           return $string;
         }
      </code></pre>

and it would render correctly, regardless of how much it's actually indented in the code.

Some preliminary research links for ignoring first/last lines:
