Man there is not added any shader, read again. Or you mean after Brian answer with added...
If Brian answered the PM of your friend with " Added " like this one :
(http://i.imgur.com/kvXQiG5.png) and you didn't get anything then I'm pretty sure he sent the wrong account name or something similar so this if your friend PM'ed him again to fix the mistake he did I don't think it will be count as an edit as he didn't request anything that changes the shader. If Brian didn't answer with "Added" then be patient and he will add it as soon as possible.
