You’ll need to use the output filter to modify the date, as the format is not editable through the shortcode. Something like this would go in your functions.php file:

Bill, this is a great plug-in! There was a small error in your filter code, which i have updated below.
add_filter( 'display_posts_shortcode_output', 'be_display_posts_date', 10, 7 );
function be_display_posts_date( $output, $atts, $image, $title, $date, $excerpt, $inner_wrapper ) {
// Change the date
if ( $atts['include_date'])
$date = ' <span class="date">('. get_the_date('j/n/Y') .')</span>';
else $date = '';
// Now let's rebuild the output.
$output = '<' . $inner_wrapper . ' class="listing-item">' . $image . $title . $date . $excerpt . '</' . $inner_wrapper . '>';
// Finally we'll return the modified output
return $output;
}
Good catch! Yeah, this code was untested so I just copied the date part directly out of the plugin. Since the attributes haven’t been parsed yet, your approach is needed. I’ve updated the code.
Another approach would be to check if( !empty( $date ) )
