[Nix-dev] Set locale in a pure nix-shell

[Kirill Elagin]

Ok, as it always happens, immediately after sending the message I realised
that I need `LOCALE_ARCHIVE` in the environment.
So `glibcLocales` is no needed at all, it's just enough to point
`LOCALE_ARCHIVE` to the system locale archive.

But the question remains. I feel that setting locale by default to
something more reasonable than POSIX might be a good idea…
