This seems like a logical improvement.

Wrong DOC here ...

class Mage_Adminhtml_Helper_Catalog_Product_Edit_Action_Attribute extends Mage_Core_Helper_Data
{
    /**
     * Selected products for mass-update
     *
     * @var Mage_Catalog_Model_Entity_Product_Collection
     */
    protected $_products;

[sreichel]

Please update Mage_Adminhtml_Helper_Catalog_Product_Edit_Action_Attribute too.

The PR #2035 contains these changes too, so maybe lets merge it first and abandon this one?
