What should it do when np.argmax() gets "axis=1" argument? I see confusion
occurring with parsing the returned results for arbitrary dimension inputs.
-1 on any such PR. +1 on making sure all arg*() functions have
unravel_index() very prominent in their documentation (which it does right
now for argmax()).
