When I create a nodejs winston console logger and set `json:true`, it always output JSON logs in multiline format. If I pipe these to a file and try to grep that file, my grep hits only include part of the log line. I want winston to output my log lines in JSON format, but not to pretty print the JSON

Here is my config (coffeescript, apologies):

```
winston = require 'winston'
logger = new (winston.Logger)(
  transports: [
    new winston.transports.Console({
     json: true
    })
  ]
)

```

And some sample output:

```
{
  "name": "User4",
  "level": "info",
  "message": "multi line whyyyyy"
}

```
