Correctly identified, but the above is not the definition of
`font-latex-jit-lock-force-redisplay' as shipped with 11.88.3.  So it
seems you have an old auctex/font-latex.el laying around somewhere in
your `load-path' which overrides the one of 11.88.3.

Do M-x list-load-path-shadows RET to find out.  The version you are
supposed to use should reside in ~/.emacs.d/elpa/auctex-11.88.3/ (or
~/.emacs.d/elpa/auctex-11.88.4/ if you updated to the newest release).

Bye,
Tassilo
