I think the point in this specific change was that numpy.histogram
previously returned invalid results when normed=True and explicit bins
were given; the previous code always normalized the results assuming the
bins were of equal size.
Moreover, I think it was not obvious what "normalized" results should
mean when one of the bins is of infinite size.
