 OK so my guess is confirmed.

 I'll refer to my email from 2012-07-15:

 I wouldn't want to break threading - so simply removing it always is
 not the way to go.
 I think for now it would be enough to remove these headers when a user
 forwards a message.
 For later we can come up with additional scenarios (i.e. user hits
 reply but removes the original sender from the recipient list).
