--------------------------------------

I plan to commit soon and backport everything to 4.x but the changes entry and the DocIdSetIterator.docID()
javadoc change.

> Today DocIdSetIterator.docID() can either return -1 or NO_MORE_DOCS when the enum is
not positioned. I would like to only allow it to return -1 so that we can have better assertions.
> (This proposal is for trunk only.)
