Make --no-recursive the default

[papandreou]

There's a bit of evidence that --recursive is causing confusion and is hard to control:

• How do you NOT recursive
• Multiple calls to subfont causing errors

We've previously talked about defaulting to non-recursive mode when we do the next major release. I'm leaving this here so we remember :)

I'm on board with this. Not entirely sure when we should do a major version increase
