 > > The -v flag of r.to.vect allows to use the pixel values of a CELL
 raster as category values of the created vector features. In that case and
 in certain circumstances it might not be necessary to create a database
 table for the output vector. It would thus be nice if r.to.vect had an
 option that would allow not to create an attribute table if the -v flag is
 used.

 > The change is slightly different than requested: the creation of an
 attribute table can also be suppressed if the -v flag is not used, in
 which case a warning is printed out that raster values will be lost.
 Sometimes it might be useful to just have e.g. areas or lines with a
 unique category and the raster values are no longer needed.

 Thanks ! I agree with your version of the change.

 Won't have the time to test, though, as I'm leaving on vacation in a few
 hours...
