I totally agree, that's ugly, but I don't have a good idea for how to
fix it yet.

(And I don't want to do anything more than the simplest possible code
moves at this stage, since I think restructuring like this would have
to be done at the end of the merge window to avoid major disruption to
people working on this code.)

Thanks for taking a look over it!
