Minor code cleanup

[dontdream]

In the function get_the_content() after the lines:

	$_post = get_post( $post );

	if ( ! ( $_post instanceof WP_Post ) ) {
		return '';
	}

the additional test:

	if ( null === $post ) {

will always return false, and could be removed for clarity.

Please ignore - I didn't notice that get_post() could find a post even if $post is null.
