That should be recorded in the ufunc's main docstring, e.g.
numpy.add.__doc__, since that is what people will actually be calling.
No one will explicitly call numpy.add.__call__(x,y).

Meh. All it can usefully say is "Refer to the main docstring." Which
is more or less what it currently says.

enigma that is made terrible by our own mad attempt to interpret it as
though it had an underlying truth."
