This is incorrect. A child of "" matches the empty path segment. Most of
the time this is used to handle a URL that ends in a "/" but an empty
segment is also legitimate in the middle of a URL.

For instance, the URL "/foo/bar/" translates to segments of ("foo",
"bar", ""); "/" translates to ("",); "/foo//bar" translates to ("foo",
"", "bar").

In Nevow, you handle unmatched children by overriding locateChild(self,
ctx, segments) or, in the case of a rend.Page subclass, providing a
childFactory(self, ctx, name) method.
