Yeah I made it as far as planning out a change to the `jj config --help` output to at least link to the documentation and then realized that my copy didn't have the documentation. Oops. And then I got occupied by some other FOSS bug and forgot to circle back.

Unfortunately there was a gap between installing it and trying it for the clever merge resolution use case I had in mind, and I've forgotten how I installed it, so I need to reverse engineer that to figure out how I got here.
