/**

This outputs:

$ g foo:target
Running "foo:target" (foo) task
foo
{
  "bar": {
    "minify": false
  }
}

Done, without errors.

but I would hope that it outputs:

$ g foo:target
Running "foo:target" (foo) task
foo
{
  "bar": {
    "minify": false,
    "scripts": ["a", "b", "c"]
  }
}

Done, without errors.
