ENH: Power ufunc raises error for integer to negative integer powers.
This is a change in behaviour. Previously
* zero to negative integer powers returned least integral value.
* 1, -1 to negative integer powers returned correct values
* all remaining integers returned zero when raised to negative integer
powers.
All of these cases now raise a ``ValueError``. It was felt that a simple
rule was the best way to go rather than have special exceptions for the
units. If you need negative powers, use an inexact type.
