What about this?

```ruby
copy_static_file 'config/locales/pt-BR.yml'
copy_static_file 'config/locales/devise.pt-BR.yml'
copy_static_file 'config/locales/admin.pt-BR.yml'
copy_static_file 'config/locales/app.pt-BR.yml'

git add: 'config/locales/*.yml'
git commit: "-qm 'Add pt-BR locale files.'"
```
