[issue7830] Flatten nested functools.partial

[Alexander Belopolsky]

Alexander Belopolsky <belopolsky at users.sourceforge.net> added the comment:

I am attaching a patch, issue7830.diff, that takes an ultra-concervative approach: partials are only flattened if both outer and inner are of exact functools.partial type and the inner partial does not have __dict__.
