Bug#624218: apt: No option to completely disable TranslationIndex downloads

[Max Bowsher <maxb@f2s.com>]

Package: apt
Version: 0.8.13.1
Severity: normal

I have explicitly set:

Acquire::Languages:: "none";

However APT still attempts to download TranslationIndex files.

Looking at the code in debReleaseIndex::ComputeIndexTargets(), there
does not seem to be any way to turn this off.

Suppressing translation downloads completely is useful when you are
on the end of a high latency link where every round trip time is
noticable, or when you are in a buildd-like chroot where humans will not
be interacting with the chroot's package information at all.
