Use IGNORE_EXCEPTION_DETAIL in doctest runner
Use IGNORE_EXCEPTION_DETAIL in doctest runner

In Python 3, the output of tracebacks now includes the module name of
the exception. This fails in doctests because they compare the output of
code. Luckiy, doctest has an existing flag, IGNORE_EXCEPTION_DETAIL,
that ignores some trivial details and, starting from Python 3.2, also
ignores any information relating to the module containing the exception.
As the flag exists in older Python versions too, just pass it to our
doctest runner always.

This means that in Python 3.1 some doctests will fail even though they
behave correctly.
