> FuzzyQuery builds a set of levenshtein automata (one for each possible edit
> distance) at rewrite time, and passes them between different TermsEnum
> invocations using an attribute source. This seems a bit needlessly
> complicated, and also means that things like visiting a query end up building
> the automata again. We should instead build the automata at query
> construction time, which is how AutomatonQuery does it.
