With USE="doc" the GNOME packages behave like what you expect but it's
the USE="-doc" case that's in question here. With USE="-doc" you don't
get any use flags installed normally and if it's in the tarball and is
always installed then there is no doc in IUSE either. Global use flags
should behave about the same for both on and off cases.
