    Attachment: LUCENE-1134.patch

The fix is very trivial. Which tests should I run to ensure this doesn't break anything?

> BooleanQuery.rewrite does not respect minNumberShouldMatch if the number of clauses is 1. This causes inconsistencies for the queries "+def" and "+abc +def", while setting the minNumShouldMatch to '1' for both.
> For the first query, results are returned although there are no SHOULD clauses in the query.
> For the second query no results are returned.
> The reason lies in the optimization BooleanQuery.rewrite has for one clauses queries.
> Patch included - optimize the query for a single clause only if the minNumShouldMatch <= 0.
