Unfortunately this makes it look like you're including text from a 
different message (i.e. quoting another message), and is more

"You can have these freedoms until I decide otherwise for my own 
reasons" is not a grant of free license. We should only accept 
freedoms that are granted in the presumption of good faith; i.e. that
