Comment:
In 1.4, the docstring is now
{{{
Factors the matrix `a` into ``u * np.diag(s) * v.H``, where `u` and `v`
are unitary (i.e., ``u.H = inv(u)`` and similarly for `v`), ``.H`` is the
conjugate transpose operator (which is the ordinary transpose for
real-valued matrices), and `s` is a 1-D array of `a`'s singular values.
}}}

Is this more to your liking? We can close this when we update NumPy to
1.4.
