This commit also includes: - whitespace / code formatting fixes - slight syntax related changes: except <exception_name>, e -> except <exception_name> as e - 3 pointless instructions instances have been rewritten [sorted] (spotted by semi-automatic check) The unrelated changes shouldn't have any real impact on whipper's behaviour.
