For me this solves both my bugs and the one reported by Helena (when going
through the extra snap step), i.e. no more extra lines and no holes (after
snapping).
However, the following:
g.region vect=precip_30ynormals
v.voronoi in=precip_30ynormals out=precip_voronoi
still gives me a polygon containing two points (39 and 82 - see
bug_voronoi3.png)
