There seems to be a bug in set_string_function when resetting the formatting function to the default. After doing that the dtype of the array that is printed is the character string, not the numpy type. Example:
.. code-block:: python
In [1]: a=arange(10, dtype=uint16)
In [2]: a
Out[2]: array([0, 1, 2, 3, 4, 5, 6, 7, 8, 9], dtype=uint16)
In [3]: set_string_function(lambda x: str(x*2))
In [4]: a
Out[4]: [ 0 2 4 6 8 10 12 14 16 18]
In [5]: set_string_function(None) # reset to default
In [6]: a
Out[6]: array([0, 1, 2, 3, 4, 5, 6, 7, 8, 9], 'H')
The ability to reset the function by using None as argument was introduced in #949.
