Default to pretty output

[bgeuken]

I have to admit that I rarely use this tool. So I hardly represent the usual daps user. Though I think it would be better to default to the --pretty output and make the other, machine readable, output optional.

Björn, I guess this is about the various list-*files commands?

How about making it always "pretty" whenever the output goes to STDOUT ( [[ -t 1 ]] ) and "flat" whenever being piped or in a subshell, unless you say --pretty?

Fixed with commit b008650

Tanja, this affects documentation. Handing over to you.

@sknorr Yes, that's the one I meant
