When `--inline-errors` is false (default) cli output looks like this:

    info: Beginning Dredd testing...
    fail: POST /machines duration: 5091ms
    pass: GET /machines duration: 2232ms

When `--inline-errors` is set to true, the cli output looks like this:
```
info: Beginning Dredd testing...
fail: POST /machines duration: 1449ms
fail: body: The ‘mesage’ property is required.

request:
host: machines.apiary.io
port: null
path: /machines
method: POST
headers:
    Content-Type: application/json
    User-Agent: Dredd/0.2.0 (Darwin 13.0.0; x64)
    Content-Length: 45



expected:
headers:
    Content-Type: application/json

body:
{
  "mesage": "Accepted"
}
status: 202


actual:
headers:
    content-type: application/json
    date: Thu, 16 Jan 2014 16:19:26 GMT
    x-apiary-ratelimit-limit: 120
    x-apiary-ratelimit-remaining: 114
    x-apiary-transaction-id: 52d8068d15c6d30200016a12
    content-length: 27
    connection: keep-alive

body:
{
  "message": "Accepted"
}
status: 202

pass: GET /machines duration: 330ms
```
So `fail` is called twice: once to say it failed, again to show the fail info.
