It already is in the regress_log_*, but I agree, it'd be good to add it to the
normal output in the failure case.

I think system_or_bail() might be the wrong tool here. If I understand
Test::More's BAIL_OUT() correctly [1], it'll prevent other tests from running as
well. Which doesn't seem quite right for a failure like this?

Kinda seems like nearly all of our uses of system_or_bail() are bad?
