Oh, right.

I thought about those and it seems insignificant. The size of the encrypted 
blob is a good proxy for that information anyway. Big? Attachment. Small? 
No.

AOL. It would seem to serve the case where the user uses two clients, both 
of which display whether a message has an attachment and neither of which 
displays any other information from inside the blob. In particular, neither 
can display an excerpt of the text, or any information about the kind of 
attachment.
