Tools inheriting from MutatingCommand print out the change they are going to make and then ask the user to confirm that this is indeed what they wanted to do. The change is outputted as a list of updated values in the form key -> [oldValue, newValue] e.g. dnsPaused -> [true, false] This CL will change the output to be clearer: key: oldValue -> newValue e.g. dnsPaused: true -> false ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=170853745
