My bad!

When you run varnishd -d from a terminal you may send CLI commands
from stdin and read responses from stdout. So whether it's in a VTC
log or run interactively, I think it would be harder to read the JSON
output (parsing with eyeballs=).

So my thought was that varnishd -d should stay human-friendly and
stick to plain text.
