We better ask Stefan (CC'ed) who I believe designed the original strategy of inserting closing delimiters in the previous electric-pair-mode. That didn't change in my redesign. FWIW, I think cc-mode should rather use post-self-insert-hook instead of redefining commands for keys whose expected behaviour is (with minor variations presumably covered by abundant hookage) self-insertion. If you place your specific cc-mode processing late enough in the hook then its insertion will be "complete" for all practical purposes. João
