I did interpret Eli's remark about "SMIE-based engines" as the simple
minded approach used by CC-mode which to my knowledge often does not
stop long before reaching the nearest "open paren in column 0".  I did
not intend to relate this to smie.el but it's obvious that I created
that impression.  Sorry for that.
