That sounds good (and I don't care too much about the name as long as it
it is in the per-hook subsection like this).

I like this, too.

No, I didn't. :) I think "stop" is good. If the others are
report-any-error and report-any-success, then the matching name for this
could be report-first-error.

Maybe report-all-errors would indicate that it was going to run all of
the hooks. I dunno. I think the documentation you wrote is plenty clear
