Add delimiters to raw output

[sigmaSd]

This is useful for external programs that wants to parse the output.
Without a delimiter like its currently the case, its impossible (as far as I know) to parse it correctly.
Also visually it looks more organized.

Well, I thought one could parse it according to the timestamps, but it would definitely be easier this way. :)

I'm wondering: do you think it would make sense to only print Refreshing in case there's actual data? Or do you think it would be more convenient for the user to be aware that there was a refresh without any new data? I'm on the fence on this one, tbh :)

I had the exact same hesitation :p I just ended up copying what nethogs does. But now that I think more about it, I think it would look better without those blank refreshing, what about something like "Refreshing:\n no data.." or do you prefer it removed?

[imsnif]

I like that idea. How about making it "Refreshing:\n no traffic"?

[imsnif]

Maybe something like <NO TRAFFIC> to make it clearer? Not sure. Whatever you feel looks good :)

[sigmaSd]

I think <NO TRAFFIC> looks good indeed!

Awesome. Thanks again! :)

Thank you too!
