Error text doesn't render properly

[BrianJKoopman]

The errors that are multi-line, like this one:

sorunlib/src/sorunlib/_internal.py

Lines 48 to 49 in bfa059c

	error = f'Task {op} in Agent {instance} failed to complete " + \
	"successfully.\n' + str(response)

They don't render properly, it ends up looking like this in stdout:

Failed to perform uxm_relock on OCSClient('det-controller-c1s6'), removing from targets list.
Task uxm_relock in Agent det-controller-c1s6 failed to complete " +             "successfully.
