Comment 14 for bug 129769

Thanks, Julien. I'll apply this, although I'm going to rename debian/dirs to debian/xscreensaver.dirs; this means the same in this case since xscreensaver is the first package in debian/control, but in a multi-binary package it makes it a bit clearer what's going on, and that's how the xscreensaver packaging does other things right now.
