Thanks Huidae! Nice.

The origin of my problem was that v.clean sends all it's output to
stderr instead of stdout, so real warnigs and errors are mixed with
normal output.

v.clean is very verbose and I would like to prevent it from filling my
screen with tones of output when called from a script, on one hand, yet
on the other I can't send all it's output to /dev/null as I want to
keep warnings and errors visible.
