   Please explain to me why g.region -l shows region corners outside the
coordinate values shown by g.region -p. Makes no sense to me when they are
both run from the same location/mapset:

GRASS 6.4.0svn (Oregon):/usr4/grassbase/Oregon > g.region -p
projection: 99 (Lambert Conformal Conic)
zone:       0
datum:      nad83
ellipsoid:  grs80
north:      46.15916
south:      41.933088
west:       -124.719106
east:       -116.644278

GRASS 6.4.0svn (Oregon):/usr4/grassbase/Oregon > g.region -l
