[Michael Barton]

Thanks Helena. Nothing wrong with the current street data. It is v.net.steiner that has a problem.

I'm trying to make some additional suggested enhancements to the documentation to make this complex but useful set of modules more accessible. I'll copy you along with Moritz and Markus.
