-------------------------+--------------------------------------------------
 When using r.proj in GRASS 7.0 (svn) going from one lat/lon location to
 another (so just to move rasters without reprojecting), I have noticed
 that the bounding box printed by entering "r.proj -g" or "r.proj -p"
 extends a half-cell-size short of the size of the input raster map. I
 interpret this to be that the bounding box is defining itself by the cell
 centers rather than their edges, and am concerned that this bug may also
 exist for performing real projections but would have remained unnoticed in
 going from one coordinate system to another.

 Please let me know if you would like me to submit more information and/or
 help in fixing this in some way.

 Cheers,

 Andy Wickert
