   If I create a new map of a box that is slightly smaller in are than the
large stream/river map, and use the 'not' operator with v.overlay, will this
be a quicker way of trimming off the lines external to the new box?

   If so, I can keep creating new boxes, each smaller than the last, and clip
the line map in smaller bites.
