annotate -d doesn't respect model_dir config

[khaiql]

In the auto_annotate_model.rake file, I have setup model_dir config to generate nested Rails engines model folders. Something like this:

 'model_dir' => 'app/models,engines/engine_1/app/models,engines/engines_2/app/models',
 'root_dir' => '',

Running annotate -d doesn't remove annotation in the nested models. But it works when I had to specify directly with --model-dir arguments:

annotate -d --model-dir app/models,engines/engine_1/app/models,engines/engines_2/app/models

So I expect when running annotate -d alone, it should pick up the same model_dir config, right?
