Bug#1001819: apt: how to set option lang to an empty list in sources.list?

[Andreas Beckmann <anbe@debian.org>]

Source: apt
Version: 2.3.13
Severity: normal

Hi,

I'd like to disable downloading translations for a single package
repository (which doesn't have them and therefore produces a lot of
noise). Adding option '[ lang= ]' to the corresponding sources.list
line seems the natural solution, but I cannot find any syntax that
achieves my goal "do not download any translations for this repository"
apt-get always errors out with some kind of "missing value".
