[PATCH 2/3] kconfig and lxdialog, kernel 2.6.13.4

["Fao, Sean" <sean.fao@capitalgenomix.com>]

This patch is a functionality modification to lxdialog to add support 
for an "Abort" button in *addition* to the standard "Yes" and "No" 
buttons on the "yesno" dialog.  The intended purpose of this patch is to 
give users the ability to abort their last requested action.
