Ok, I actually wanted to something like that for a while already but
I wasn't familiar with dh_listpackages, that sounds like a solution.
Thanks!

What happens however if the user sets DEB_BUILD_OPTIONS=nodoc ? It
sounds like we would still want to have an additional 'else' branch to
check that value.

Ok, with 'nodoc' set we are already generating an empty -doc package
so this would work anyway without this, but it makes sense to have it.

I'll look into that.
