Notes
Fix in nagios-plugins project: https://github.com/nagios-plugins/nagios-plugins/commit/e8810de21be80148562b7e0168b0a62aeedffde6
monitoring-plugins upstream does not plan to make an upstream change similar to
nagios-plugins because there are valid usecases to execute stuff locally via
check_by_ssh (although not commonly known and used).
