    gvfs-mount: Handle the ask-question signal
    
    Present questions as a message and a numbered list of choices such
    that the user must enter one of the numbers.
    
    For example:
    """
    Can't verify the identity of ...
    This happens when you log in to a computer the first time.
    
    The identity sent by the remote computer is ... If you want to be
    absolutely sure it is safe to continue, contact the system
    administrator.
    [1] Log In Anyway
    [2] Cancel Login
    Choice: 1
    """
