We generally don't accept patches on bugs.python.org. Please open a pull request on github, see https://devguide.python.org/#contributing

Dilyan, please explain what you believe the problems to be and how the patch solves it.  These seem to be 3 separate issues.

Do not change idlelib.config.  config_main.def contain 'default = True' or 'default = False' and that is what the docstring references.

The variables got_it in distutils/command/sdist and quote in email/_header_value_parser can be skipped making the code shorter and faster.

The risk of introducing a bug is higher than the minimal benefit of making the changes.  Thus we do not typically accept changes like this.  We'll clean up such code when we touching it for other reasons.
