Subject: py: Clean up commented-out code and comments about exception
 hierarchy.

In CPython, EnvironmentError and IOError are now aliases of OSError so no
need to have them listed in the code.  OverflowError inherits from
ArithmeticError because it's intended to be raised "when the result of an
arithmetic operation is too large to be represented" (per CPython docs),
and MicroPython aims to match the CPython exception hierarchy.
