commit cb390522ea713a08a43799fbc1884fb7ad480784

    Really fixed the atan2(-Pi, 0) bug.
    
    The problem was that atan2_eval assumed that if y is real and not
    positive, it must be negative. But this neglects the fact that in
    symbolic compution it may just not be possible to determine the
    sign. Now, the expression is returned as it is. Ugly, but correct.
