That's a new one to me, but I have never claimed to be an expert on these things. I was always taught that punctuation goes outside of quote marks unless it is part of the thought inside the quote marks...but our public information officer tells me that it all goes inside. So, there you go. Punctuation and grammar are fluid with the common usage of the times...not necessary written in stone. I will,however, fight the misuse of aphostrophes with my last breath.
