/bin/garn: line 2: warning: setlocale: LC_ALL: cannot change locale (C.UTF-8)

Hello,
I'm trying garn on macOS, I'm seeing this warning every time I run garn command

$HOME/.nix-profile/bin/garn: line 2: warning: setlocale: LC_ALL: cannot change locale (C.UTF-8): No such file or directory

This is the result of running locale

LANG=""
LC_COLLATE="C"
LC_CTYPE="UTF-8"
LC_MESSAGES="C"
LC_MONETARY="C"
LC_NUMERIC="C"
LC_TIME="C"
LC_ALL=

Does this happen for garn build and garn check as well as garn enter? And do you see the logs the same number of times?

Yes, it happens with all commands.

executing head -n 5 $HOME/.nix-profile/bin/garn gives this result:

#! /nix/store/zzpm4317hn2y29rm46krsasaww9wxb1k-bash-5.2-p15/bin/bash -e
export LC_ALL='C.UTF-8'

It looks like this environment variable was changed from LANG to LC_ALL in ae69820. LANG was originally introduced in 3e52fd0.

I've removed the variables completely in 665f623, but haven't opened a PR yet since I'm not sure of the ramifications. In my limited testing though I am still able to nix profile install garn and everything seems to work well both inside and outside of the garn repo -- the environment variable isn't set on my system. LANG is set, but calling garn with LANG='' garn also seems to have no noticeable impact on it. Can anyone see any reason not to remove these?

Fixed in #422. Will be released in v0.0.17.
