[geos-devel] Polygon::getBoundary() return

[strk at refractions.net]

To conform to OGC specs I made
Polygon::getBoundary return a single LineString
when no holes are present.
This had to be handled in MultiPolygon::getBoundary()
as well, but was missing. It is now fixed.

testLeaksBig.xml runs again w no failures.

--strk;
