> 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.
