;;; test-text-config.el --- Tests for text-config -*- lexical-binding: t; -*-

;;; Commentary:
;; Covers cj/prettify-compose-block-markers-p, the prettify-symbols compose
;; predicate that forces org src-block markers (#+begin_src / #+end_src) to
;; compose while deferring to the default predicate for everything else.
