[Message part 3 (text/plain, inline)]

Evaluating the following forms after launching `emacs -Q' yields `(wrong-type-argument number-or-marker-p nil)':

    (require 'smie)
    (smie-backward-sexp-command)

This is due to `smie-backward-sexp-command' not checking whether `n' is `nil' before passing `(- n)' to `smie-forward-sexp-command'.
