Bug 175314 Delete commented code in WorkbenchActionBuilder
WorkbenchActionBuilder has about 225 lines of code commented out in createHelpMenu. From the looks of it, this was added as test code when the command handler work was first being done. It was introduced in revision 1.16 by cmclaren. I'm going to delete it.

    private IWorkbenchWindow getWindow() {
        return window;
    }
    /**
     * Hooks listeners on the preference store and the window's page, perspective and selection services.

    private void hookListeners() {
        pageListener = new IPageListener() {
            public void pageActivated(IWorkbenchPage page) {
                
            }

            	((RetargetActionWithDefault)buildProjectAction).setDefaultHandler(buildHandler);
            }
        };
        getWindow().addPageListener(pageListener);
        prefListener = new Preferences.IPropertyChangeListener() {
            public void propertyChange(Preferences.PropertyChangeEvent event) {
                if (event.getProperty().equals(
                        ResourcesPlugin.PREF_AUTO_BUILDING)) {
                   	updateBuildActions(false);
                }
