Not only that. By clever branch factoring, you can possibly get yourself
rid of lots of deep levels. As in:

static void blah(void)
{
	if (foo) {
		bar;
		bar2;
	} else {
		if (this) {
			that;
			that2;
		} else {
			bad day;
			bad day2;
		}
	}
}

xfrmd:

static void blah(void)
{
	if (foo) {
		bar;
		bar2;
		return;
	}
	if (this) {
		that;
		that2;
		return;
	}
	/* yay, got rid of two levels of indent! */
	good day;
	good day2;
}
