 your initial idea of "g.region -a vect=mmmm res=xxxx" solves it. Set the
 resolution to 1000 there (or whatever) and the -a flag will ''always''
 grow outwards in all 4 directions. So you run the above, then run g.region
 a second time with your finer resolution. If your second finer-resolution
 fits evenly in the initial coarser one, you now have a grown region with
 bounds rounded to nice whole numbers, a bit bigger than your points map so
 catching them all!
