hm. ok. it's more complicated. we need to make a difference between --debug messages from
pca.pl and also included wget screaming, which is printed on stderr as well.

if we aren't interested for both, 2>$file catches a plenty of unwanted stuff. The best (but
the most complicated) solution will be to set a default behaviour of global --debug swith
and then add there a few new switches which would granular and override global --debug like
followings:

--debug
--debug-file=$file ## pca's debug messages
--debug-wget=$file ## separated wget output

regardly to this approach, probably something like --debug-patchadd=$file or so would be handful too.
