Yes, I outdid myself with the parentheses, sorry about that. The code:

var drag = new OpenLayers.Control.DragFeature(pointlayer,{
                onStart: function(feature, pixel)
                {
                        storeGeometry(feature.geometry);
                },
                onComplete: function(feature, pixel)
                {
			processNewGeometry(feature.geometry);
                }
        });

        drag.dragHandler.stopDown = false;
        map.addControl(drag);
        drag.activate();
        map.events.register("click", map, function(e) {
              var lonlat = map.getLonLatFromViewPortPx(e.xy);
              alert("You clicked near " + lonlat.lat + " N, " +
                                          + lonlat.lon + " E");
        });

What I want to do is to preserve 'click' functionality even if the click 
happened over a draggable feature. pointlayer is a GML layer containing 
features with point geometries. What happens in the svn version is that in 
pointlayer.events, Events.js on line 627, after Handler.Drag returns 
continueChain = true due to the stopDown property, but on the call to the 
next listener (a Handler.Feature), continueChain = false and thus it doesn't 
fall through to other elements. I'm still familiarizing myself with OL 
structures, so my assessment might be wrong of course...
