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. */
