I'd actually suggested a new map, something like "document.commands" that would be where the existing and new commands could be listed and replaced. E.g.:

var c = document.commands;
var b = c.bold;
c.bold = function(range, defaultUI, value) {
   // call original or do your own processing here
   return b.apply(this, arguments); // no-op
};
