there's some strange coastline data near longitude 180. See eg

I thought I'd ask before trying to fix this, in case I'd flood the  
world otherwise.

I haven't found an editor that works well in this area -- they all  
seem to think the world ends at ±180 degrees. Here's a challenge:  
Which editor will be first to support seamless editing all around the  
world? (Let's leave the poles out for now.)

For testing, I traced a small lake crossing the line as a single  
closed way with natural=water: http://openstreetmap.org/browse/way/31254026 
. That's good data as far as I understand the data model. It'd be nice  
to have a reasonably well-mapped area across this meridian as a  
testing ground for tools.
