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.
Some of this seems to be debug code which has been left in, some of it
seems to just be old code that was commented out and never put back in
and probably just forgotten about. Either way, we use git for a reason,
so there's no need for these code snippets to stick around. The code
history can be inspected and old code retrieved that way.
