Possibly missing fences and accents in the MathML Operator Dictionary

Hi all,

The Asana Math font [http://tug.ctan.org/pkg/asana-math] contains 
various glyphs to stretch mathematical operators but some of them are 
not included in the MathML Operator Dictionary. Here is the list (I use 
the Unicode names):

- LEFT SQUARE BRACKET WITH QUILL, RIGHT SQUARE BRACKET WITH QUILL, LEFT 
S-SHAPED BAG DELIMITER, RIGHT S-SHAPED BAG DELIMITER which seem to be 
stretchy fences.

- COMBINING TILDE, COMBINING OVERLINE, COMBINING BREVE, COMBINING CARON, 
COMBINING LOW LINE, COMBINING DOUBLE LOW LINE, COMBINING DOUBLE 
OVERLINE, COMBINING LEFT HARPOON ABOVE, COMBINING RIGHT HARPOON ABOVE, 
COMBINING LEFT ARROW ABOVE, COMBINING RIGHT ARROW ABOVE, COMBINING LEFT 
RIGHT ARROW ABOVE, COMBINING WIDE BRIDGE ABOVE which seem to be stretchy 
accents. Note that most of them already have a "non-combining" version 
in the dictionary and that the circumflex accent exists in both 
versions. Also, breve is not stretchy in the operator dictionary, while 
it looks like the author of Asana Math wants it to stretch.
