From 2275d502114c71045af991697048191fed88aac4 Mon Sep 17 00:00:00 2001
From: Frank Lichtenheld <frank@lichtenheld.de>

Subject: config: Add --null/-z option for null-delimted output

Use \n as delimiter between key and value and \0 as
delimiter after each key/value pair. This should be
easily parsable output.
