I think that's OK with me, anyway. You'll recall that I initially requested
that you split this into two patches, after all.

Would you like me to post a follow-up that does the refactoring that Jason

opinion about how this should be done, so rather than drive you crazy with
debating, maybe that would be smoother?  :)
