"bodyTokenReplace" function does not implode the array values to new line

Hi,

In the ContentNotifyManager.php file, "bodyTokenReplace()" does not implode the "[content-notify:digest-nodes]" (included in the mail body) to the new line. All the nodes in the array appear in a line. is it possible to provide a fix for this? or is there any hook I can use to modify it to my requirements?

Thanks
