From: Randy Dunlap <rdunlap@xxxxxxxxxxxxx>
Update Documentation/kbuild/kconfig.txt, which mostly contains
user help for using the kernel config tools.
- Add mention of 'nconfig' embedded help text.
- Make the section on new config symbols readable.
- Correct how to find menuconfig search help.
- Add section on 'nconfig' usage.
- Mention that gconfig has multiple viewing modes/options.
