As far as I'm concerned:

	if (c1) {
		if (c2)
			s1;
		else
			s2;
	}

is good, but:

	if (c1) {
		if (c2) {
			s1;
		} else {
			s2;
		}
	}

is better.  if a programmer adds a statement (e.g. a debug printf) at
a random place, or uses a (poorly-written) macro that happens to be
multiple statements in place of, say, s2, "it all just works."
