Constructor InterpolatorFilterReader( Reader in, Interpolator interpolator, RecursionInterceptor ri ) ignores RecursionInterceptor parameter

```
    public InterpolatorFilterReader( Reader in, Interpolator interpolator, RecursionInterceptor ri )
    {
        this( in, interpolator, DEFAULT_BEGIN_TOKEN, DEFAULT_END_TOKEN, new SimpleRecursionInterceptor() );
}
```

Is this to provide backward compatibility with a previous release? or it is a bug?
I can provide a patch if needed.

TIA,
Gabriel
