Subject: Use path coercion in track iterators
X-Git-Url: http://git.tdb.fi/?a=commitdiff_plain;h=02453a447bad0ecc2a71e00b9578c9afaee0eadb;hp=02453a447bad0ecc2a71e00b9578c9afaee0eadb;p=r2c2.git

Use path coercion in track iterators

This enforces common traversal rules in all places.  It also fixes a bug
in TrackOffsetIter where moving to a turnout from an endpoint not on the
selected path would potentially cause an out-of-range iterator to be
created.
