I certainly tried my best to satisfy both the BSD license and Sergey's wishes, but if you can obtain Sergey's explicit approval of such an arrangement, that would be great, and I would have no problems going ahead and merging that PR and other fixes. Specifically what I do not want to happen is a situation when the BSD license was perhaps followed, but the result was not what Sergey intended, and he would feel that we stole his work. In other words, merging code to SymPy's master against the original author's will is questionable (ethically and perhaps even legally, I am not sure). So if you could obtain Sergey's permission, then we can go ahead, as far as I am concerned.
