bug#25784: 25.2; mouse-1 binding in debbugs-gnu.el

[charles@aurox.ch (Charles A. Roelli)]

Thanks for looking into this, Michael.  I realize now that this change
only makes sense if mouse-2 sets point when clicked, as it does in Gnus.
I think what follows is the correct way to do it, and it works as
expected.
