  I'm not crazy about the shape this makes the API, as I'd rather we didn't start growing awareness of filtering in layers this high.
  
  I think we can probably kill contrib/simplemerge entirely - it's had nothing but cleanup changes and a feature removal since May of 2007, and I can't fathom a use for it today. Let's see if we can get consensus around that on the mailing lists and then hopefully simplify this a TON.
