[PATCH] kconfig: menuconfig: change "---" items to "-*-", "-M-" or "- -"

[Matej Laitl <strohel@gmail.com>]

This little patch changes notation of unchangeable menuconfig items to always
reflect the current state of inclusion of a feature.

Hi again, Sam, Roman, Randy.

Instead of incorporating all changes into a single patch, I decided to split 
things into more rather independent patches.

Expect another one extending show_help(). (which ATM needs more polishing 
before being posted)
