[Debian-science-sagemath] 62 failed tests and classification of remaining failures

Thanks, I've confirmed that this fixes the issue. However it hasn't been applied upstream yet:

https://github.com/sympy/sympy/blob/master/sympy/core/function.py#L767

Could you give me some more details on why the patch is necessary? That would help me convince the Debian SymPy maintainer to accept it.
