Aptitude has pretty good searching features. With ?origin() or ~O you
can select packages by their origin. For example, this prints packages
which are installed but their origin is not Debian:

    aptitude search '?installed?not(?origin(Debian))'

I don't know what is the origin string of debian-unofficial.org but the
search string could be something like this:

    aptitude search '?installed?origin(debian-unofficial)'

See /usr/share/aptitude/README for more information about Aptitude's
features.
