I don't see the optional specification in the docstring.  Perhaps
because mode=None in the signature?

The reason is that then, if you do not specify the signature (as in
your case), you get the following helpful message:

ValueError: Keyword "mode" must be a function or one of ['reflect',
'linear_ramp', 'edge', 'constant', 'minimum', 'wrap', 'symmetric',
'median', 'maximum', 'mean'].

Instead of

pad() takes exactly 3 arguments (2 given)
