      I think it is a good idea to keep vimrc_example.vim as short as
      possible. It only contains things that "everybody should use".

      The default value for 'formatoptions' is "tcq". You propose to add
      "rol" here. "r" and "o" are for adding the comment leader, "l" for not
      breaking lines that were already longer than 'textwidth'. I don't
      consider these helpful enough to set by default.

      The "l" flag has limited effect, when typing a string literal that
      crosses "textwidth" it still gets broken.

      "r" and "o" are typically for when a file type has comments and depends
      on what kind of comments could be wrapped properly.
