 More "config-based hooks".

I know Emily's keen to get to the conclusion of the "config-based-hooks"
story. I think it's gotten a lot of careful review already, and it would
be nice to have it land soon in this cycle so the follow-up topics can
be queued after it.

I re-rolled it a ~week ago[1], but that was a trivial change to save you
from dealing with a compilation error as it got merged with my own
"ab/run-command" (it was using "env", not "env_array")[1]. Other than
that there's been no change to it for the last month since the v4[2].
