Hmm... it's hard to say. ;)
Maps looks nicer in MapSource&Co with --no-trim, if you generate sea. On 
the other hand it could cause problems, because coastline-nodes aren't 
counted and so a tile could get to big for mkgmap. Eg. if you generate a 
map of Italy you may get hole coastline of  Adria. So in this case it 
would be better not to extend the map like --no-trim did.
