Subject: v.to.points: a pair of identicaly located points in output when the
input is a closed line
Platform: GNU/Linux/x86
grass obtained from: Trento Italy site
grass binary for platform: Compiled from Sources
GRASS Version: cvs 2005.01.10
When v.to.points is run on a closed line, there will be one pair of identicaly
located points - one will be the "starting" point with cat=1 and along=0.0,
and the other will be the "ending" point of a line (which is exactly the same
as the "starting" since this a closed line) with the maximum "cat" and "along"
attribute of all.
It took me quite some time to sort it out. It's not documented. Looks dumb obvious
now to me, as there is the "along" calculated by default. But could there be
at least a switch to turn this behaviour off? When transforming my isolines to
points I need only one point per one x,y with the attribute copied form the input
line. And I guess this is the default behaviour users would normally expect from
v.to.points.

Of course this can be workedaround by v.clean to remove duplicate points. Yet
a switch to avoid producing duplicate points at all would be handy.
Reassigning to wish6.
