$rename documentation should explain the behavior when the original field isn't present

XMLWordPrintableJSON

      The documentation at http://www.mongodb.org/display/DOCS/Updating#Updating-%24rename doesn't specify the behavior of $rename when the source field doesn't exist and the destination field does exist. I believe the current behavior is to unset the destination, which was very surprising to me at least.

      Thanks!
