When setting up my work PC, I used my private setup scripts. They automatically set my git user.name and user.email with --global

After pushin commits to the private work organization I saw my private account showing up there which is not what I wanted. I would have been able to identify that problem early if screenfetch would have displayed the email address that was configured globally (because screenfetch is a command executed in my .zshrc)

Also, to see even easier which is used, the GitHub picture could be displayed

This seems pretty edge case. I could possibly write up a module for the upcoming fetch project I'm working on, but I'm not sure this fits into screenfetch that well.
