Another common reason is that people don't know how to use continue.
Eg, instead of writing:

	for(p = example; p != nil; p = p->next) {
		q = p->fish;
		if(q->foo > 4 && q->bar < 3) {
			r = q->blarg;
			if(r->foo == 7) {
				dosomething(r);
				r->done++;
			}
		}
	}

it is stylistically preferable to write

	for(p = example; p != nil; p = p->next) {
		q = p->fish;
		if(q->foo <= 4 || q->bar >= 3)
			continue;
		r = q->blarg;
		if(r->foo != 7)
			continue;
		dosomething(r);
		r->done++;
	}

Notice the difference this makes in the indentation.
I think it's also slightly more readable, but YMMV.
