Thank you.  Done.

I noticed one thing while testing the new feature.  I suspect we do
not want to generate metapackages (as in entries in debian/control)
for such enhancing packages.  At least, I suspect we should have a way
to avoid generating metapackages for tasks.

Here is a draft patch doing that.

         print "Package: $task\n";

         my $header;

Not sure if this is the best way to handle it.  Perhaps better to have
a separate task header for this, like the leaf header used to control
tasksel tasks.  What is your view on this?

Happy hacking,
