How to get all your set git options:

    git config --global --get-regexp . | sort -u

A hack I like that makes diffing possibly minified or formatting-mangled source files easier:

    diff.css.textconv css-beautify

(Unminifies and unifies the formatting of css files before diffing them, might need to have the *.css type set in your .gitattributes though)

    core.editor nvim

(Use neovim as the editor for commit messages and other things)
