    Description

      Robert Engels suggested the following idea, here:

      http://www.gossamer-threads.com/lists/lucene/java-dev/54217

      When merging in the stored fields from a segment, if the field name ->
      number mapping is identical then we can simply bulk copy the entire
      entry for the document rather than re-interpreting and then re-writing
      the actual stored fields.

      I've pulled the code from the above thread and got it working on the
      current trunk.
