I counted the roundabouts because they seem to be the only
affected elements of this flag and I thought it might be easier
to find a clean cut between different "dol" and "dor" areas.
The code for that is simple enough.

I never liked the idea that an option called check-xxx is
also changing the data, although I am not sure if this still
happens today.

Okay, if I got it right we just have to add a few lines in StyledConverter.
I'll post a patch for this.
