Git repository status as shown in tmux powerline

[ChHaeni]

Hi,

I created a gist that describes a possible way how one can integrate the buffer-related repository status in lualine. This can be useful, if you have files from different repositories open in one nvim session...
I've got the idea from the tmux powerline.

I thought this could be something that lualine users might be interested in, so I share it here -> link to gist

If you have suggestions on how to improve my code, I'd be very happy to hear them!
