Hmm. This seems to make "make oldconfig" a _lot_ more verbose than it
used to be. In a very annoying way.

I'm used to this (v2.6.35 "make oldconfig" with no changes):

   [torvalds@i5 linux]$ make oldconfig
   scripts/kconfig/conf -o arch/x86/Kconfig
   #
   # configuration written to .config
   #
   [torvalds@i5 linux]$

but now it prints _everything_. The old "oldconfig" only printed
things out when there was something to be asked about.

This is a regression.
