;;; Commentary:
;; Provides commands for explicitly unfilling (ie. unwrapping)
;; paragraphs and regions, and also a command that will toggle between
;; filling and unfilling the current paragraph or region.
;; Based initially on Xah Lee's examples, and later rewritten based on an article by Artur Malabarba.
