Great, thank you! (following up here for posterity; discussed via IRC)

As we discussed, we should formalize some CC-ing of the security list,
or a separate security team for reviewing patches (for public flaws,
rather than reporting them). And making sure "[security fixes]" is
noted, as you did here, for easy sorting.

In any event, patch looks good and as a leaf with a pretty trivial
patch, I think you would be clear to push directly to begin with. There
was some discussion a while back at what is "trivial," but a version
update with 1 dependent is about as easy as it gets. Perhaps another
thing to make sure we are on the same page about but I doubt anyone
would complain if you had pushed this directly.

We could also let QA build, since it is back up, but again, very minor
concern here if something were to break.

Anyway, please do push! I might put "[security fixes]" before the period
in the commit message to match previous ones, but that is very minor.

Thanks again!
John
