FormHelper#label ignores translated attributes

With the i18n support of rails, you may translate the attributes of a model like this:

en:
  activerecord:
    attributes:
      user:
        name: User name
        email: Email address

But if you use

form_for @user do |f|
  f.label :user
  f.text_field :user
end

rails will print out "User" instead of "User name"
