I tried to come up with a simple patch to achieve this, but I think
this is beyond me, particularly since I think something different has
to happen for these cases:
np.array([1234, 'ab'])
np.array([1234]).astype('|S2')
I tried a few things (changing the rules in PyArray_PromoteTypes(),
other places), but I think I'm more likely to break some corner case
than fix this cleanly.
I filed a ticket (#1990) and a pull request to add a test to the 1.6.x
maintenance branch, for someone more knowledgeable than me to address.
I tried to write the test so that either choosing dtype=object or
dtype=<string of the required length> would both pass.
