Hi Robert,

you're right, `jit-lock-force-redisplay' has been recently changed,
see  Maybe
there is a good reason behind the change of arguments number, but I
simply don't know it.  I can see two solutions:
- report this to Emacs and make them restore backward compatibility;
- implement `font-latex-jit-lock-force-redisplay' in AUCTeX without
relying on possibly existing `jit-lock-force-redisplay'.
As a temporary fix, I'm going to change
`font-latex-jit-lock-force-redisplay' following the second solution.
