Adding . and .. was a mistake by itself. I never needed them, but always had to write conditions to skip them when traversing the file system. Also, dotfiles don't work well with masks because `*` doesn't match dot-files, and `.*` match all dotfiles including . and .. which causes many programs to fall into endless recursion (for example, `du -sh .*`). Everything related to dotfiles in Linux is done wrong.
