LUCENE-3849: fix some more test only TokenStreams
> position increments should be implemented by TokenStream.end()

>
> if you have pages of a book as multivalued fields, with the default position
> increment gap
> of analyzer.java (0), phrase queries won't work across pages if one ends with
> stopword(s).
> This is because the 'trailing holes' are not taken into account in end(). So
> I think in
> TokenStream.end(), subclasses of FilteringTokenFilter (e.g. stopfilter)
> should do:
> {code}
> super.end();
> posIncAtt += skippedPositions;
> {code}
> One problem is that these filters need to 'add' to the posinc, but currently
> nothing clears
> the attributes for end() [they are dirty, except offset which is set by the
> tokenizer].
> Also the indexer should be changed to pull posIncAtt from end().
