Line Item Example code passes wrong arguments to commerce_product_line_item_configuration

The line item example calls commerce_product_line_item_configuration like so:

commerce_product_line_item_configuration('example_line_item');

but according to http://api.drupalcommerce.org/api/Drupal%20Commerce/ommerce--modules--pr... it should be passed like this

commerce_product_line_item_configuration(array('type' => 'example_line_item'));
