bug#15443: hs-forward-sexp design issue

[Andreas Röhler]

hs-forward-sexp insists to be called with an argument

    (funcall hs-forward-sexp-func arg)))


That way it's not possible to instrument hs-forward-sexp-func just saying

(search-forward "something")

Instead

(lambda (arg)(search-forward "something"))

would be required.

As it's a function to be set by modes/users

life will be easier if this argument is optional.

Thanks!
