Most of the change is about using the new private member delimiters_ instead of the "delim" table. Also, we don't display an icon when the delimiter is one character. I did not manage to let the combos expand to the maximum. git-svn-id: svn://svn.lyx.org/lyx/lyx-devel/trunk@17727 a592a061-630c-0410-9148-cb99ea01b6c8
