Problem to solve

As Squeak Developer, I want format comments from legacy methods in my squeak image so that my squeak image has nice and clean formatted methods and comments everywhere and not empty lines.

Acceptance Criteria

• Using commented Legacy-Code (maybe even a little to much commented) I can Poppy-Print the code to fit in the rest of my codebase style-wise. Not only does the code get formatted but also the comments fit in nicely creating very well-looking and well-readable code/comments.
• new lines are kept except two in a row
• empty lines are deleted
