The problem is spuriously re-asking a question that *has already 
been answered by the user*, and if the user accidentally just 
accepts the default, the config breaks.

We try to keep things working fine across 'make oldconfig', i.e. 
if the .config worked before, it should work after a 'make 
oldconfig' as well.

Thanks,
