Hi all,

attached is v3, only small changes:
1) the message "maybe duplicated OSM way " was printed too often
2) with --x-cycle-map, change the headings
at junctions with only three different arcs so that angles of 90° or more
are created.

If I hear no complains I'll commit this patch on monday,
probably without the --x-fix-sharp-angles switch.

I am still trying to work out in what case the Garmin routing algo
prefers a detour, so maybe I find more improvements later.

Ciao,
Gerd
