better dummy method for gettext + rails 2.2

Here's a better dummy method that also handles the
"this is %{jo}" % {:jo => "so"} cases.

class Object
  def self._(msg)
    return msg
  end
  def _(msg)
    return msg
  end
end

class String
  alias :__old_format_m :%
  def %(hash = {})
    if hash.kind_of?(Hash)
      ret = dup
      hash.keys.each do |key, value|
        ret.gsub!("\%\{#{key}\}", value.to_s)
      end
      return ret
    else
      ret = gsub(/%\{/, '%%{')
      ret.__old_format_m(hash)
    end
  end
end

- Looking forward to a working rails 2.2 gettext plugin.
