Coastline doesn't have to be a single closed way.

And natural=water does.

(Or at least, if the rules have changed then the rendering for mapnik
will be wrong).

Which, as far as I'm concerned makes the test completely useless for
natural=water. Does anything actually rely on it? The wiki page says
its important but doesn't say *why*?

Have a nice day,
