[Numpy-discussion] np.diff on boolean arrays now raises

There is an ongoing discussion on github:

https://github.com/numpy/numpy/issues/9251

In 1.13 np.diff has started raising on boolean arrays, since subtraction of
 boolean arrays is now deprecated.

A decision has to be made whether:

   - raising an error is the correct thing to do, and only the docstring
   needs updating, or
   - backwards compatibility is more important and diff should still work
   on boolean arrays.

If you have opinions on the subject, or enjoy arguing for the sake of it,
please share your thoughts either here or on github.

Thanks!
