I was just facing this problem. I solved it by adding event listeners to the polyline path, which is implemented as an mvc array. I used the mvc array events documented here:
https://developers.google.com/maps/documentation/javascript/reference#MVCArray

Once you have your polyline set up:

var path = poly.getPath();
google.maps.event.addListener(path, 'insert_at', function(){
alert("path insert_at event");
}); 
google.maps.event.addListener(path, 'remove_at', function(){
alert("path remove_at event");
}); 
google.maps.event.addListener(path, 'set_at', function(){
alert("path set_at event");
}); 

Hope that helps.
