When operating on an array whose last dimension is unity, the default behavior of argsort is not very useful:

Sorry, but I don't think we are going to add a special case for this.

I don't see this as a special case. When axis is unspecified, the default is axis=-1, which causes argsort to operate on the last dimension. A more sensible default would be the last non-unity dimension.
