Actually, this just needs dropping from profiles profiles/info_vars, though I'd personally prefer dropping it from the USE_EXPAND output (there's also LC_ALL and LANG displayed, so it makes sense to keep it in one place)
We can have it automatically filter any variable that's both in info_vars and USE_EXPAND from the USE flags output. However, that's misleading because it makes it appear as if none of the linguas_* flags are set when some of them actually are set. I think it's cleaner if we just accept the redundancy or remove LINGUAS from info_vars.
(In reply to comment #2) WONTFIX is just fine w/ me :)
To clarify, the first LINGUAS is an environment variable and the second one represents USE="linguas_en_GB linguas_en_US linguas_en linguas_nb_NO linguas_nb linguas_no". They're two different things that are related, but they're not really redundant. It's just a side-effect from the way that USE_EXPAND maps environment variables into USE flags.
