Contributions summary:Maciej primarily focused on enhancing the functionality of the `multiple-cursors.el` package. Their contributions included implementing the `mc/mark-all-dwim` command, refining its behavior, and adding associated tests. Further modifications involved making `mc/mark-all-dwim` behave differently based on prefix arguments and correcting logic within `mc/mark-all-in-region` to prevent infinite loops. These changes demonstrate a focus on feature implementation, testing, and refining user interaction within the Emacs environment.
