Vetle Leinonen-Roeim commented on KAFKA-9479:
---------------------------------------------

The changes I've made will also affect when printing states in other 
situations, for instance supplying multiple groups instead of {{--all-groups}}: 
{{–group group1 --group group2}}. Is this acceptable, or should we make an 
effort to only do this change for {{--all-groups}}?

> Describe consumer group --all-groups shows header for each entry

> It would be nice if we did not show the header for every entry.
