I totally agree, and that behavior matches the current ('1.0.2') docstring.

so sad -- could this be deprecated. I know we had a pretty length 
discussion about this issue in another context. In general, it's a bad 
idea for methods to sometimes return copies and sometimes views -- it's 
begging for subtle bugs!

oh well, either the code or the docstring should change, in any case.
