No, the relevant strings don't have another face. Before I tried adding
the read-only property, I just had:
,----
| (font-lock-add-keywords nil `((,(regexp-quote "{++") . cm-addition-face)) t)
`----
and that worked fine. Changing that line to
,----
| (font-lock-add-keywords nil `((,(regexp-quote "{++") . '(face cm-addition-face read-only t))) t)
`----
made fontification of the relevant strings stop working. After changing it to:
,----
| (font-lock-add-keywords nil `((,(regexp-quote "{++") 0 '(face cm-addition-face read-only t))
`----
fontification worked again.

Ah, ok, it makes sense now. Thanks for the explanation.
