Ah damn :( Apologies for that!
 
I was hacking around with `make webpages` to check the rendering and
clearly forgot to run `make check`. I'll make sure to configure Travis
CI.

Separately, I had tried to post the initial patch to the mailing list
to get some feedback but `git send-email` was failing to send it, not
sure why. I figured that as the original patch only really appeared on
Rusty's radar that posting just the "documentation" fixup for review
might've lacked context, but clearly I should've done so (and clearly
it was more than "just" documentation).

Thanks for cleaning up after me :/
