Is your goal to have this merged into the kernel source tree?
If so, you should also send the patch the the kconfig maintainer and
mailing list.

The output is quite verbose in its default mode (no options specified).
To get something useful, I use -C -O -N.

For my uses and preferences, I would like to see a -D (e.g.) which
is just a combination of -CON. And it would be nice if that was the
default mode also. :)
