[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.

Not a bug but a "bad feature". Although the curent behaviour is not
good, I'm affraid it cannot be changed during GRASS 6 devel line not to
brake software that might depend on it. Please fill a defect report in
Trac and the issue maybe will be fixed in GRASS 7.
