[PATCH 26/33] kconfig: strip 'CONFIG_' automatically in kernel configuration search

[Sam Ravnborg <sam@ravnborg.org>]

From: Bernhard Walle <bwalle@suse.de>

Modify the ncurses configuration tool ('make menuconfig') in a way that the
user can enter the search string (/) both with or without the leading
'CONFIG_'.

This simplifies using copy & paste from .config files because you can
select the whole word.
