[SciPy-Dev] stats cleanup, attempt

Hi, Slowly but surely I am making some progress with respect to understanding the stats library. Hence I feel can start with making some contributions too. As a first attempt I would like to propose some clean up first. There is some code from https://github.com/scipy/scipy/blob/master/scipy/stats/distributions.py#L415 to https://github.com/scipy/scipy/blob/master/scipy/stats/distributions.py#L430 This is not used in distributions.py, and if I recall from a previous mail from Josef it not used at all anymore. Can I remove it? BTW: should I post a mail about proposals like this, or just remove it, and send a pull request with some explanation? Nicky
