--format option does not work for dns record-sets export

[GoogleCodeExporter]

What steps will reproduce the problem?
- run: gcloud dns record-sets --format json -z <your-zone>  export dns.json

What is the expected output? What do you see instead?
- the dns.json file contains the YAML format instead of JSON.
- Also the command output prints and extra "[]":

> gcloud dns record-sets --format json -z <your-one>  export dns.json
Exported record-sets to [dns.json].
[]

What is the output of 'gcloud info'?
I have replaced some values with ellipses.

Thanks for reporting the issue.

--format flag effects console output format, and is not related to any 
particular command. [gcloud dns record-set export] command supports only yaml 
format.

The documentation for the command can be more clear. So will keep this issue 
open to address that.
