    Description

       db.getCollection('SomeCollection').find({}, {'array.0':1}) 

      I would expect the above to return documents like:

       {array:[{a:'a',b:'b'}]} 

      but instead returns all elements of the array, just as empty objects:

       {array:[{}, {}, {}]} 

      This doesn't make any sense. It seem broken.
