Use XDG_CONFIG_HOME

[Brandon Kalinowski]

This assumes that XDG_CONFIG_HOME is ~/.config

Ideally it should not. For instance, line 2 of init.vim should be:

execute 'source ' . stdpath('config') . '/plugins.vim'

I should be able to clone the repo and try it out:

git clone jarvis
XDG_CONFIG_HOME=$PWD/jarvis/config nvim jarvis
