No, not the beginning point to the end point. Either you have closed 
contours or your contours go over the edge of your current region, 
meaning that some contours are not closed. So, in order to close them, 
you can do so arbitrarily at the edge of your region by patching in a 
line that represents that edge. This line can be created with v.in.region.
