dselect dies on terminal window resize

[Tom Joseph <ttjoseph@artsci.wustl.edu>]

I've noticed that dselect will die anytime I try and resize my terminal 
window at the main menu, failing with the message "dselect: failed to getch 
in main menu: Success".  Here's a patch that fixes the problem for me.  
Comments? Any problems with it? If not can this be incorporated?

BTW, to all dpkg developers - thanks for all your hard work on such 
wonderful software!
