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

[Charles A. Roelli]

`mouse-1' is bound in debbugs-gnu.el, which means that a nil value of
`mouse-1-click-follows-link' is not respected.  The following patch is
needed:

There already was a ChangeLog entry to this effect in the past:

2012-12-23  Lars Ingebrigtsen  <larsi@gnus.org>

        Don't explicitly bind mouse-1.

        As Michael Heerdegen <michael_heerdegen@web.de> says:

        However, also binding mouse-1 is not necessary.  Depending on the 
        setting of `mouse-1-click-follows-link', which is non-nil by default, 
        mouse-1 already follows links - see its doc.  We should leave it up to 
        the user if he wants to use mouse-1 for following or not.

But the change does not seem to have been made, or maybe it was reverted
at some point.
