 Ciphertext uses `font-lock-keyword-face', plaintext uses
 `font-lock-string-face', comments use `font-lock-comment-face', and

+checkpoints use `font-lock-constant-face'.  You can customize the
 display by changing these variables.  For best results, I recommend
 that all faces use the same background color.
