Fix for cancelling a scale/shear still going ahead with the operation

Detail:
  The shortcuts F4 (Scale X), Shift-F4 (Scale Y) and Ctrl-H (Shear) could not be
  cancelled. Pressing ESC (or clicking outside the window) performs the action
  as if you had pressed Enter, which is not the case if reached via the menus.
