[mkgmap-dev] Commit: r1577: When adjusting turn headings apply all relevant adjustments.

Version 1577 was commited by markb on 2010-02-18 20:39:48 +0000 (Thu, 18 Feb 2010) When adjusting turn headings apply all relevant adjustments. Previously, if a heading needed adjusting because the delta from the outgoing arc was too small, it did not then consider whether the delta from the incoming arc was too small also. Now, it considers both cases and adjusts the heading as appropriate.
