Addressed PEP-8 incompatibilities detected by pep8.py (Issue 117). Note that this file uses two-space and not four-space indentation, also complained about by pep8.py - this will (hopefully) be fixed in a separate commit since it's such a massive change. Moreover, since indentation change would make more lines excessively long the latter haven't been fixed yet either.
