-loadtxt raises TypeError instead of ValueError when fname is wrong type
------------------------------------------------------------------------
-``numpy.loadtxt`` now raises a `TypeError` instead of a `ValueError` when the
-type of the ``fname`` parameter is incorrect.
-
-Previous behavior::
-
-    >>> np.loadtxt(1)  # doctest: +SKIP
-    Traceback (most recent call last):
-       ...
-    ValueError: fname must be a string, file handle, or generator
-
-Current behavior::
-
-    >>> np.loadtxt(1)  # doctest: +SKIP
-    Traceback (most recent call last):
-       ...
-    TypeError: fname must be a string, filehandle, list of strings,
-    or generator. Got <class 'int'> instead.
