Bound error on ParallelFor conversion

[fredericDelaporte]

ParallelFor(1, 100, ...) is converted to Task.WhenAll(Enumerable.Range(1, 100)... while it should be Task.WhenAll(Enumerable.Range(1, 99). (#63)

ParallelFor semantic is "first included last excluded", while Range semantic is "first included, total count".
So if we have ParallelFor(a, b, ...), the conversion should yield Task.WhenAll(Enumerable.Range(a, b - a)....

This was spotted with nhibernate/nhibernate-core#1455 test.

Thanks for the report, I completely forgot about this.
