Comment 6 for bug 1479110

I'm a bit torn. Honestly, the spec option number 2 in Dan's graphical represenation is the least intuitive to me. Option 3 is simpler than 1 and I want to prefer it but .... option 1, how it currently works, is probably how I would guess it works and more intuitive. I can't pull out of memory an example but I want to say that it's closer to how other options have worked elsewhere in Evergreen (though I can't think of the actual example off hand).
