Author: barendgehrels
Date: 2013-11-11 17:36:57 EST (Mon, 11 Nov 2013)
New Revision: 86627
URL: http://svn.boost.org/trac/boost/changeset/86627

Log:
[geometry] Fixed self-turn points, neighboring function in get_turns did have the wrong meta-function. Also cleaned corresponding unit tests / added test cases for reported error (reported by Joan on mailing list)
