Hmm, the comment in the preprocessor is all of those:
    case '(': case '{': case '[': case '%':
      /* '\(', etc, can be used at the beginning of a line in a long
         string split onto multiple lines with \-newline, to prevent
         Emacs or other text editors from getting confused.  '\%' can
         be used to prevent SCCS from mangling printf format strings.  */
