Fix <shift+enter>

When hitting `<shift+enter>` it does a line break `<br>` but then wraps the new line into a paragraph such as:

    <p>Now that there is the Tec-9, a crappy spray gun from South Miami.
        <br>
        <p>This gun is advertised as the most popular gun in American crime. Do you believe that shit? It actually says that in the little book that comes with it: the most popular gun in American crime. Like they're actually proud of that shit.</p>
