The `# self.comment = comment` caught my eye while working on #9071 as well as the intermediate variables, which aren't really needed. As a result, I reformatted the code slightly in those places.
* Remove comment in AugeasCommentNode.__init__
* Replace some intermediate varibles with return-statements in apache augeas parser.
* more clean-up
* Fix dangerous default argument
* Remove unused imports
* Remove unnecessary comprehension
* Use literal syntax to create data structure
* Use literal syntax instead of function calls to create data structure
