suppress tranlation checks when executing aptitude update

I usually get the following  messages when aptitude update is executed

Ign http://security.debian.org wheezy/updates/main Translation-pl

These messages are printing on the terminal, and it makes a whole process slow. In order to prevent to access any Translation-* while updating, I execute the following command as root

$ echo 'Acquire::Languages "none";' > /etc/apt/apt.conf.d/99no-translation

It create 99no-translation file in /etc/apt/apt.conf.d/ directory, and the file has Acquire::Languages "none";
