Re: narrow-to-defun and mark-defun now work properly for CC Mode.

Both before and after fontification
with what amounts to  emacs -Q -D  , but more on the command line,
both     C-s method
and      M->
are fast, very fast.

Fontifying the emacs/src/xdisp.c buffer took nearly 5 minutes.

I found the   emacs/src/xdisp.c  buffer and in it, I did:


    M-:
        (progn (load "elp")
               (elp-instrument-function 'font-lock-fontify-buffer)
               (elp-reset-all))
    RET

    M-x font-lock-fontify-buffer RET

    M-:
        (elp-results)
    RET
