I've adjusted the commit log to fix various typoes.

And instead of calling this through PYTHON_TARGET_FINALIZE_HOOKS, I
called it explicitly in PYTHON_CREATE_PYC_FILES, before doing the byte
compilation. The two are very closely related so I believe it made more
sense this way.

Applied with those changes. Thanks!
