William Carroll 718899c629 More Elisp linting
In order for this to scale, I need to solve two things:
1. Ad-hoc ignore fill-column rules for URLs and other exceptions.
2. Run Elisp flychecker without evaluating my Elisp code and firing its
   side-effects.

;;; kbd.el --- Elisp keybinding -*- lexical-binding: t -*-
;; Author: William Carroll <wpcarro@gmail.com>
;; Version: 0.0.1
;; URL: https://git.wpcarro.dev/wpcarro/briefcase
;; Package-Requires: ((emacs "25.1"))
;;; Commentary:
;; In order to stay organized, I'm attempting to dedicate KBD prefixes to
;; specific functions. I'm hoping I can be more deliberate with my keybinding
;; choices this way.
;;
;; Terminology:
;; For a more thorough overview of the terminology refer to `keybindings.md'
;; file. Here's a brief overview:
;; - workspace: Anything concerning EXWM workspaces.
;; - x11: Anything concerning X11 applications.
;;; Code:
