I do understand that there is no OSM relation ID for generate-sea, but
I do not understand how there could be no way ID.  The natural=coastline
are genuine OSM ways, aren't they?

Why are these messages generated?  Generate-sea is not complaining anything,
now that my script strips any incomplete islands from the extract and patches
the mainland coastline so that it will reach the tile borders.  Also the map
is looking good.  It is not really a big deal.  I have been grepping away
the generated IDs from the output, in addition to selected IDs that I have
analyzed before (splitter or Geofabrik's osmosis problem).
