             *   a dot is encountered followed by a newline OR
             *   two consecutive newlines (horizontal whitespace is taken into
             *   account to consider spacing errors)

             *   encountered followed by an @ and word characters (a tag).
             *   This is optional.
             * - Tags; the remaining characters
