Log files don't have line breaks

[BoyCook]

When appending console output to log files need to retain line breaks.

Yes, that is needed.

I've added '\n' as below and it helps :)

this.logToFile(util.format('['+ new Date().toISOString().replace('T', ' ').substr(0, 19) + '] ' + 'Updating repo [%s]'+ '\n', repo));
