Just a heads-up to people: since I made my turn-announcement changes, I've noticed that I don't get proper (for some definition of "proper" :-D) announcements when turns come in quick succession. (It happens that the last three turns to my house are under 100m apart, so I get a lot of chances to test it.)

I'll look at the code when I get a chance and see if I figure out why I broke it or how to improve it. Meanwhile, if your map shows a bunch of turns close together, be alert!
