This is possibly a bug. I also had no luck with ->set_point, it was just
ignored (yes, I don't like warnings ;), at least with version 0.7007. I
didn't check 0.7008 yet.

I'm very interested in the answer ;) For example I don't like they way
of navigating up and down, skipping virtual wrapped lines. I would
prefer just walk through any visible line, independent from being part
of a wrapped line or not.
