[GRASS-user] v.info vs. r.info: different region output format

Hi list,
I've tried to create bounding boxes for all layers of a given location 
with an extern python script.
This script parses the output from "v.info -g <layer>" resp. "r.info -g 
<layer>".

But I noticed, that in a location with a geographic crs, the region 
outputs (esp. the unit formats) of vector and raster layers differs from 
each other.
v.info prints the region in decimal degrees (DD) whereas r.info produces 
an output in degrees,minutes,seconds (DMS).

For example (nc_ll location from www.grassbooks.org; EPSG:4001):

  > v.info -g precip_30ynormals
  north=36.49917
  south=33.99472
  east=-75.62194
  west=-84.02389
  top=1615.440000
  bottom=2.438400

  > r.info -g elev_ned_03arcsec
  north=35:54:40.666666N
  south=35:35:17.334885N
  east=78:27:08.335106W
  west=78:49:17.333333W

Is there any reason for the different outputs or is this a bug?

For parsing both ouputs with external tools, it would be better if the 
formats were equal.
