Michael McCandless commented on LUCENE-2160:
--------------------------------------------
Hmm... isn't there a danger here that a field rename would change the term sort
order?
Ie, terms in the terms dict are sorted first by field and then by term text.
Seems like this tool could break that, in the index?
