Remove trailing spaces

[xstable]

The whole file is indent two spaces.
Is it possible to remove those spaces?

So the file will not be longer:

---
  param1:
    name: test

but

---
param1:
  name: test

Even an Option to remove the trailing --- would be nice.

I had a the same problem and I did it with regex, but maybe there is something else, better solution for it. ;)

I can see this isn't fixed yet. So just a quick regex replace (like @mrkitan's suggestion) for those who doesn't have time to wait/send a PR like me.

let yaml = YAML.stringify(this.matterObject).replace(/^[\s]{2}/gm,'');
