Hi Marek,

> This allows the scrub command to scrub without asking the user if he really

This is _really_ hackish and makes an effort not to fit into the coding
style at hand.  Please use the available code and extend the construct
below to match the ".quiet" suffix.  It is not that different.

Urgh.  Please turn this into

if (scrub) {
   if (!scrub_quiet) {
   } else {
   }  
}
