Done, it is ticket 1562: http://projects.scipy.org/numpy/ticket/1562
Note, there is no patch yet because I have not come up with an elegant way
of doing it.

Also, in the process of putting together that ticket, I discovered two more
bugs related to atleast_?d() functions.  They are tickets 1559 and 1560,
both have patches.
