Comment 25 for bug 1214176

I'm not sure about this, typically going back and changing/modifying existing copyrights isn't something that's generally acceptable. I realize this is a specific case, but I still am not sure if this is the correct thing to do or if it's necessary at all.

I'd like to get some guidance here from folks that are more copyright savvy than I am, as copyright headers have been a touchy subject in the past.

My understanding int he past was you can append to/add but you can't remove or modify.
