Correct.

AFAIK, this only started happening about a year ago.  Yes, it's mildly
annoying; but I'm happy there's a bidirection interface at all.

Before then, ruby-core could not get duplicate messages from redmine
when a reply hit ruby-core first before hitting redmine.

I prefer Redmine suppress the duplicate mail like it did before;
at least it should be easier to have threading headers preserved
(In-Reply-To/Message-ID).
