I'm trying to use a commit hook that runs eslint. To hook uses `GIT_DIR` to find the package local eslint and related eslint configs. Like this:

```
ESLINT_PATH="${GIT_DIR}/../node_modules/.bin/eslint"

```

From the command line, this works fine. `GIT_DIR` is set and everybody is happy. In GitKraken though, `GIT_DIR` is missing. In fact, no git environment vars are set. I ran `env` in the hook and looked at the output.

Is this normal behavior for GitKraken? Is there some hidden config that I'm missing? 

I can mod the script, so if there's a more "proper" way to do this, I'm all ears.
