I am not keen on this change: I think the user should always be able to
force the default output by setting command line options (which should
protect against future changes in the default). Thus I would like to
continue to allow  --output=sender --output=recipients. 

I do approve of making the default do something useful but whether it
should be both or just sender (which is much faster) is unclear to me.

Best wishes

Mark
