As it's a minor improvement, and I tend not to like unnecessary
interdependence of series in my tree (until they are in char-misc
and hence no chance of them changing), I'm fine with not using
that new functionality here. 

That will change once it's upstream of course!

I will send a pull request to Greg nice and early this cycle
so that should be in my upstream soon.

I'm also fine with you using this if you want to though!
