Well my idea was to make sure that anything inside the given polygon  
is exported; so part of a segment lies within, it gets exported, and  
if one single segment of a way lies within, then the way will also be  
exported. But looking at it now, you are right... while it makes  
sense to export a way of which you do not have all segments, it does  
not make a lot of sense to export a segment of which you only have  
one node. (Unless that segment were tagged and would lend some  
meaning to the single node, but we don't want tagged segments.)

So yes, I'd say it is sensible to accept Robert's suggestion.
