[SciPy-Dev] scipy.stats.signaltonoise docstring

[David Goldsmith]

Hi, folks!  The docstring for scipy.stats.stats.signaltonoise says that if
axis == None, the input is first ravel'd, but I see no code that does this;
here's the code:

def signaltonoise(a, axis=0, ddof=0):
    """..."""
    a = np.asanyarray(a)
    m = a.mean(axis)
    sd = a.std(axis=axis, ddof=ddof)
    return np.where(sd == 0, 0, m/sd)

Even though it's not surrounded by an "if axis is None:", I checked the
docstring for asanyarray anyway, and there's nothing there about
raveling.  So, what gives?
