- Show error message based on return code rather than messages in
stderr.
- Don't decorate the message paragraph with alert color, we are already
doing that by showing a message at the top.
- Untabify.
- Improve message showing that upgrades are running, gramatically.
- Show errors messages decorated as errors.
- Minor cleanups.
- Remove emacs mode line as emacs automatically detect Python files
based on the #! line.
- End comments with a '.'.
- Use single quotes instead of double quotes for string for consistensy.
- Update message to say that it take more than a minute to finish
upgrades. Some times it takes a lot more than that.
