Trailing underscores in types

[KendrickLamarck]

Trailing underscores in types in the Parameters and Returns sections have to be escaped in order to not give an Unknown target name warning.

Examples that DON'T work :

def identity(object_):
    """Identity function.

    Parameters
    ----------
    object_ : Any

    Returns
    -------
    object_ : type(object_)
        Just `object_` again.
    """
    return object_

The returns section

Returns
-------
type(object_)
    Just `object_` again.

Without a name doesn't work either. In both cases, I have to write type(object\_).

I don't know if this is fixable like it was for parameter names (#63). I guess types are actually supposed to be links sometimes, in contrast to parameter names? Feel free to close if that is the case and there's just not really a possible fix.

I think we try to allow / stick with standard RST, and name_ in RST is a link to .. _name: whatever. So I don't think this is a NumpyDoc issue so much as a RST one

Well, the parameter names also change the default RST behavior by making the names bold. It's just a bit confusing and inconsistent, especially because the types are in italics. This normally also disables linking, but I guess in this case the italicization happens after "link-checking", whereas bolding the parameter names happens before?

But if the intention is to allow standard RST after the :, that's a good enough reason to close this.
