Except that make mrproper deletes the .config file so I'd have to spend 
fifteen minutes with menuconfig again unless I know (and remember) to back it 
up. :)

I guess make clean is trying to avoid damaging the "make dep" output.  I 
thought that a big part of Keith Owens' new build system was to get rid of 
the horror that is "make dep", but I remember now that Linus rejected it for 
some reason.  Oh well.  Just curious...
