Hi all,

up to now RoadMerger doesn't merge (combine) two roads if the have different directions. This is OK for oneway roads but I see no need for this with other roads. The attached patch changes this. It has an influence on file size (safes a few KB in each tile) and very likely also on routing, hopefully to the better/faster.
It also reduces zig-zagging in the low-res-opt branch.

Strangely enough almost all was already implemented, so maybe WanMil (the original author) tried that before and found a reason not to do it. Will search the archives later...

Gerd
