Hi I've improved some of the logic where arcs on either side of an angle are one- way (merging, splitting or continuous). I didn't detect turn-left/right instructions rather then keep-left/right on the roads I use where there is a gradual split. However I thought this would be a possibility in other cases if the angles on the split were increased so it seemed best give an accurate representation to the device and let it announce what it considers best. One-ways merging don't need any increase in angle. Continuous one-ways were considered to be a flare, eg joining a roundabout or a more major road and the angle wasn't increased, but there are other cases where it should be, so I've removed this as a special case.

Hi Gerd & Thorsten
I need to test one more scenario where a fast one-way lane splits with equal priority (eg on a motorway) and check that my changes don't trigger a turn instruction instead of "keep-left" or "keep-right".
Please don't commit anything until I've tested this.

Hi Ticker,
the patch solves the original problem at https://www.osm.org/node/27550903 I tried to find other places where the change in the map data produce differences in routing but without success so far. I think that's good news, but all cases only involved footways or tracks so far.
So, I wait for Thorsten to confirm that the patch is an improvement.
Gerd

Hi Gerd & Thorsten
This, I hope, is the final version of the changes to AngleFixer.
I've simplified and clarified some of the logic, improved some of the diagnostics, added more comments and made better choices of when compactDir format is used. There should be a slight reduction in .img size, fewer time penalties and better turn-instructions.
