    Remove Crappy Markup from WordPress Shortcodes
    ==============================================

    When using shortcodes in WordPress like so:

    [shortcode]

    Content goes here...

    [/shortcode]

    And assuming that the shortcode wraps your content with another element, sort of like this:

    function my_shortcode( $attr, $content )
    {
    return '<div class="my_shortcode">' . $content . '</div>';
    }
    add_shortcode('shortcode', 'my_shortcode');

    The built-in WordPress `wpautop` filter will add junk markup to your output:

    <div class="my_shortcode">
    </p>
    <p>Content goes here...</p>
    <p>
    </div>

    Adding `copter_remove_crappy_markup()` to the shorcode will clean up the output:

    function my_shortcode( $attr, $content )
    {
    $clean = copter_remove_crappy_markup($content);
    return '<div class="my_shortcode">' . $clean . '</div>';
    }
    add_shortcode('shortcode', 'my_shortcode');

    Resulting in:

    <div class="my_shortcode">
    <p>Content goes here...</p>
    </div>
