Subject: Use heading difference to check if we have moved away from the old road.
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=871a78bf2f85d91252e8a14b9ed34b6a3bbba2ab;p=mapper

Use heading difference to check if we have moved away from the old road.
Remove some dead old way code.
Misc other fixes.
