[mkgmap-dev] [PATCH v1] Improve destination handling by splitting ways

There are many benefits:
1. Thight integration of process-exits and process-destination. You can 
decide via style file what happens if a link is part of an exit and 
contains a destination tag.

2. Each destination tag is taken into account. Think of a big motorway 
junction. It is possible that you have to follow several independent 
destinations within the same junction. Now you will see each destination 
on the Garmin at the right place.

3. process-destination often does not work on big motorway junctions. An 
easy example is the common cloverleaf design of junctions. The 
destinations of the inner links was not handled by process-destination 
because the resulting motorway is not unique. With the new handling you 
will get the destination hint within the cloverleaf.

4. You will get destination hints on the motorway entries. This should 
also be handled by the process-destination but on my Garmins but I think 
it is done better now.

No.

That's a problem that should be fixed with this patch.
