Ahh, so, with auto, it "just does the right thing" ?  Hmm, I don't
think I actully tried it, but assumed it wouldn't work for some
reason...  Guess what they say about 'assume' is true :)

It's "new" in 3.4.  I just disovered it a few weeks ago.  It's cool
feature and really helps with multiple ssh connections to the same
systems. It's also incredibly poorly marketed/documented :)
