CR / line break still missing

The issue brought up in “Bugs found: missing CR and wrong replacement of &” still has not been fixed: WP Robots.txt still breaks other plugins adding to the virtual robots.txt, as any trailing newline is being stripped, resulting in an unwanted joining of lines, as shown in the original post.

A fix would be to add a trailing newline in inc/core-functionality.php :

function robtxt_filter_robots( $output, $public ) {
        $content = get_option( 'robtxt_content' );
        if ( $content ) {
                $output = esc_attr( wp_strip_all_tags( $content ) ) . PHP_EOL;
        }

        return $output;
}

It would be most helpful to get this integrated. Thanks for considering.
