Git icon details
Hi,

Here is a comparison between DevOpicon and [all-the-icon](https://github.com/domtronn/all-the-icons.el/blob/master/fonts/all-the-icons.ttf)

DevOpicon is better sized and positionned, but all-the-icon is easier with commit node a bit larger. Especially when background and foreground colors are bright.

What do you think of this ? Would it be possible to improve git icon ?

Thanks for DevOpicons.
