Hmm, that is incorrect, I believe.  I have used a scalar before.  Maybe it
works because a scalar is broadcastable to the same shape as any other
N-dim array?

If so, then the wording of that docstring needs to be fixed.

No, I think Christopher hit it on the head.  For whatever reason, the
endian-ness somewhere is not being respected and causes a byte-swapped
version to show up.  How that happens, though, is beyond me.
