I've got [a bit of neovim config](https://github.com/anlsh/nvim/blob/8b61520a5ecd752427abffc45...) which sends you straight to `neogit` (which is basically equivalent as far as I use it) when a certain env var is set.

So in my .profile I've got

``` alias gg="NEOGIT_SLAVE=1 nvim" ```

It's definitely not perfect but it's good enough to work for basic committing/rebasing flows and it's faster than booting up emacs for the same purpose.
