Hi,

Unfortunately I couldn't convince the update to build (for mysterious
reasons, and I didn't have much time to diagnose), so I wrote (then
realized it was technically backported) the patch that upstream
provided in late May [0] and committed that. This works out well
because that can be MFH'd, then we can circle back on the update
soon-ish.

Patch was committed in r547124.

Thanks,

Kyle Evans
