The proposed format is not delimiter based (though intention is to make 
it script friendly, it looks like user friendly for direct reading 
purpose), and therefore Stephan suggested to make it delimiter based.

If we are not concerned about direct read since Anand proposed to 
associate the script friendly output to --mode-script, we will obviously 
choose a delimiter which is not a valid character for the value in rest 
of the fields.
