;;; +defaults.el --- measured defaults for Emacs -*- lexical-binding: t -*-
;;; Commentary:
;; I find myself copy-pasting a lot of "boilerplate" type code when
;; bankrupting my Emacs config and starting afresh. Instead of doing
;; that, I'm putting it here, where it'll be easier to include in my
;; config.
;; Of course, some might say I could just ... stop bankrupting my
;; Emacs. But like, why would I want to?
;; Other notable packages include
;; https://git.sr.ht/~technomancy/better-defaults/
;;; Code:

"Set the major mode for BUF from the buffer's name.
Do this only if the buffer is not visiting a file."
