bugfix: newline required, so when debug=true is set the config file will parse correctly.
This is strictly a bugfix for when debug=true is set.
if no newline is there, then you will get a parse error like:
policyd-spf[22092]: ERROR parsing line "skip_addresses = 127.0.0.0/8,::ffff:127.0.0.0/104,::1,10.99.8.0/24debugLevel = 4" from file "/nix/s
