[issue11078] Have test___all__ check for duplicates

[R. David Murray]

New submission from R. David Murray <rdmurray at bitdance.com>:

Inspired by what happened in issue 8973, I offer the attached patch for test__all__ to have it check the __all__ list for duplicates.  Interestingly, the first failure is not in struct, but in os.  Obviously the patch can't be applied until the test succeeds, so I'll be coming back to this later.  Figured I'd post the test patch in case anyone else wants to play with fixing things before I get to it.
