Minor updates for bzip2 compression after more review.

Browse Source 
Update error types throw by bzip2 to be more consistent with gzip.

Update the bzip2 and gzip error default to be AssertError as that's the more common case in both, and add a 'break;' to the default clause -- we don't intend to be just falling through those case statements, even if the default is the last, we should be explicit about that.

Clean up some tabs that snuck in, rename a variable to be more clear, and add some comments.
