If I run

Try: g.region vect=analytical_boundary
the raster map's region is that of the vector map. But, I don't believe
that this removes all cells beyond that region.
Advice on how to eliminate the extraneous cells (and clip the raster to
the nearest cell boundaries of the vector map) is greatly appreciated.
To be honest: until 5 minutes ago, I didn't even know that r.region
existed. I thought you made a typo. As I don't understand what r.region
is good for: I would use g.region as already said, then followed by:
r.mapcalc small_dem_east = dem_east
You could then remove dem_east, if you'd never need any DEM values
outside analytical_boundary
