If it's empty, I'll stop in the middle of the right lane. If somebody wanting to make a right turn does pull up behind me, I'll move and let them make their turn. I'll even turn around and point sometimes, asking drivers with no signal, whether they're trying to turn, if their car is "pointed" a bit to the right. But it's more often than not, that either somebody won't come up behind me, or, when they do, they'll want to go straight.

Of course, if the intersection is completely empty, with no cross traffic and good visibility, it's a moot question where to stop...
