Sorry, I mean, 1-st snippet cannot be compiled, because:

1.sp(7) : error 036: empty statement

because empty {} is not permitted.

The question is just about convenient code formatting.

Maybe just use dummy:

public OnPluginStart()
{
	int a;

	if (!foo(0, a))
	if (!foo(1, a))
	if (!foo(2, a))
		dummy();
}

bool foo(int p1, int p2)
{
	return (p1 == p2);
}

void dummy() {}

So, maybe language provides simplier walkaround instead of "dummy"?

Well, don't pay attention. Stupid question.
