summary: make status code more readable

In commands.summary(), we currently zip a list of labels with a list
of statuses. This means the order of the status list has to match the
list of the labels, which in turn means the status elements have to be
inserted into specific places in the list. Let's instead group the
labels and status data we want to display in a single list of pairs.
