[issue20842] pkgutil docs should reference glossary terms not PEP 302

[Oren Milman]

Oren Milman added the comment:

ImpImporter was first added in changeset 37808 (https://hg.python.org/cpython/rev/ccc0b5412799) and updated a day later in changeset 37821 (https://hg.python.org/cpython/rev/3135648026c4).
Both of these commits were introduced to support PEP 302. 
Since then, ImpImporter remained quite the same, and was never changed to suit later relevant PEPs (e.g. PEP 420 and PEP 451).

Thus, IMHO, we should go with your second option, Martin, and retain the PEP 302 reference in ImpImporter documentation.

With regard to the accuracy of Python's 'finder' glossary entry, it was updated recently, in changeset 99434 (https://hg.python.org/cpython/rev/88cee7d16ccb), to suit PEP 302, PEP 420 and PEP 451, so ISTM there is no need to adjust it.
