This is a new issue that gets linted with flake8 3.5.0. Basically you should
never use a blank except: statement.
This will catch all exceptions, including KeyboardInterrupt and SystemExit
(which is likely not intended). If a catch all is needed, use
`except: Exception`. If you *really* mean to also catch KeyboardInterrupt et
al, use `except: BaseException`.
Of course, being specific is often better than a catch all.

This passes `python3 -mcompileall`. Changes:
* use `0o` prefix for octal literals
* print as a function
* except .. as
* use six.reraise to replace a multi-argument raise statement
* use six.string_types and six.moves.configparser
* remove uses of `L` suffix for long integers
