I dug through close-areas.pl to see what it's doing with that stuff, and 
indeed it checks - if no coastline crosses a tile edge, it looks in 
blank for "sea" tile status.  If found to be sea, it makes the 
background blue and puts a land island on it.  If not sea, it'll check 
for 'coast' and do some magic, but in all other cases, it becomes a land 
tile with a lake on it.

Mind you, I'm not a perl guru, so take the above with a grain of salt.
