Thanks for the PR it looks good. I am good to merge this but will hold off as I think you might have made the commit with the wrong git creds (guessing the commit one is your work's 😜)

Agh, you are correct! Fixed.

No worries. For future git lets you conditionally include other files using includeIf. An example of this would be

[includeIf "gitdir:~/personal/"]
    path = "~/.local/share/git/per.conf"

per.conf could set your get creds like name, email, gpg key, etc.
This would include per.conf if the git dir path start with ~/personal as an example. This has saved me multiple times.

My setup has ~/.config/git/config loading the file ~/.local/share/git/config that is where I put per machine configuration. This file is where I have this snippet.

Hope this helps.
