The use of forward-sexp-function in up-list is indeed problematic,
although it does work 90% of the time.
We probably need to introduce an up-list-function hook. `transpose-sexp'
similarly fails in to do the right thing in some cases (tho for
transpose-sexp, the problem is not so much in the "jump over a sexp"
part as in the way it decides what to leave unchanged around point).
