In this situation. Go near a black hole, and you'll find that the other 
terms are not vanishingly small.

If that's what Kepler's law says, then GR says pretty much the same 
thing (the difference lying in those vanishingly small terms). So it's 
manifestly incorrect to say that GR cannot predict this.
