> In case you are interested in what happens in my contaminated emacs, if I run C-x = after (forward-sexp) then it says a left parenthesis, but if I use `(progn (forward-sexp)(what-cursor-position))` then it says the next character is C-j. Furthermore, changing it to (prog2 (forward-sexp) (what-cursor-position) (redisplay)) causes it to work properly (i.e. no bug).
If invoking `redisplay' fixes the problem, it means some display
optimization is misfiring. But there are quite a few of those
optimizations, so without a reproducible test case, it's really hard
to say where to look.

I agree with Antoine: if you can reliably reproduce this with your
~/..emacs, bisect it to find the minimal customizations necessary to
reproduce the problem, then post that information here.
