[as written, that example was *ugly*]

Dunno. Example - this I got from a user:


v.vol.rst -c input=utm3d at UTMfinish wcolumn=temp tension=10.
cvdev=cvdevmap38 maskmap=ter at UTMfinish segmax=698 npmin=699 dmin=150.0
zmult=50.0
6283 records selected from table
Processing all selected output files will require 0 bytes of disk space for
temp files
WARNING: Points are more dense than specified 'DMIN'--ignored 5938 points
(remain 345)
WARNING: 345 points given for interpolation (after thinning) is less than
given NPMIN=699
WARNING: There is less than 700 points for interpolation, no segmentation
is necessary, to run the program faster, set segmax=700 (see manual)

... he told me that nothing got calculated (apparently he didn't use
g.list).
Indeed the information is quite buried in above output. Also r.watershed
with multiple output does not say much.

That's why I would see the generated map names printed out.
