I want the core and the user settings on top, all but the alias sections
and sections added by plug-ins to be in alphabetical order, then the
aliases, followed by plug-in related settings (such as git-lfs).
I like having some colors for the meta-information shown during
diff operations.
Using the `diff-hightlight` script, you can get character-level
highlights of your diffs (just like GitHub and GitLab).
