indicator instead of just the indicator (which is sometime cryptic).
Ex:
before : SP
now    : SP - Smartparens Mode

* etc/NEWS: Add en entry for this new feature.
* lisp/mouse.el (minor-mode-menu-from-indicator): Append the mode name
  after the indicator when there is no menu defined by the mode.
