Custom git dir

[bennypowers]

I'm managing dotfiles with a setup based on this tutorial: https://www.atlassian.com/git/tutorials/dotfiles

tl;dr:

alias config="git --git-dir=$HOME/.cfg/ --work-tree=$HOME"

What this means is that when I'm working in ~/.config, I don't get any VGit features.

So, practically speaking: can I configure VGit to use ~/.cfg as it's git dir for files in ~/.config (even though the dotfiles setup uses ~ as work tree, on a daily basis this is only really relevant to ~/.config)
