I think that using v.centerpoint in v.points.cog would be the best, as
it would then be possible to add a pcenter= option to v.points.cog to be
able to use v.centerpoint other possibilities. 

I can do that, but I think that it is best to first commit the
translation of v.points.cog as is and in a second step add the call to
v.centerpoints instead of duplicating in v.points.cog what
v.centerpoints does.

Is it ok?
