... else what happens is undefined ...

I prefer a clearly defined logic, like the one Yonik gave above:
{code}
skipTo(n) == skipTo (n, max(doc()+1) // assume doc() initialized to -1
{code}
If this is agreeable we should check that all tests pass after modifying all
skipTo() implementations accordingly.
> Scorer.skipTo(current) remains on current for some scorers

> Background in http://www.nabble.com/scorer.skipTo%28%29-contr-tf3880986.html
> It appears that several scorers do not strictly follow the spec of
> Scorer.skipTo(n), and skip to current location remain in current location
> whereas the spec says: "beyond current".
> We should (probably) either relax the spec or fix the implementations.
