There seems to be an 'undocumented feature' when editing Lisp files
with the 'lisp' option set. I can no longer % between matching
s-expressions []{}() if they are in comments and on newlines, e.g. in:
;; myfold {{{
(blah blah)
;; }}}
;; (blah
;; blah)
I can't jump between the {} or the second (). Is this a bug?
