Also, in an ongoing effort to stop people shooting themselves in the foot,
I would suggest to add a warning to v.to.db option=perimeter that the
result is probably not what the user is after. At minimum I suggest a
paragraph in the man page explaining the fractal problem, which could 
also be a good introduction to the op=fractal dimension and compact options,
but I don't think that is enough, as many don't bother to RTFM and broken
analysis reflects badly on GRASS as well as the end-user.

if there are objections to using G_warning() as well, please speak up.
