bug#1435: C-Click on a mode in the mode-line causes crash in MacOS X

[Jason Schadel <jasons@aweber.com>]

I do have a Kensington Expert Mouse with their ancient Mouseworks  
software installed.  I wouldn't be surprised if that is the problem.

No more crashes with your update.  Here are the results:
<mode-line> <C-mouse-1> is undefined
mode-line down-mouse-3- shows the minor-mode menu
mode-line down-mouse-1- shows the mode menu
