Version 1506 was commited by markb on 2010-01-22 10:01:32 +0000 (Fri, 22 Jan 2010) When adjusting arc angles, ignore reverse arcs of oneway roads. This suppresses the spurious "keep left/right" directions that sometimes occur when a ramp joins a motorway/trunk. For oneway roads that don't allow pedestrian routing, we could probably do without the reverse arcs completely - to be investigated.
