Menu action items requiring further interaction need an ellipse (…) at the end
As per this old HIG rule:
Use an ellipsis (…) at the end of a label if further input or confirmation is required from the user before the action can be carried out. For example, Save As…, Find… or Delete….
Do not add an ellipsis to labels such as Properties or Preferences. While these commands open windows that can incorporate further functionality, the label does not specify an action, and therefore does not need to communicate that further input or confirmation is required.
I will throw a patch at this.
