[PATCH] Strip 'CONFIG_' automatically in kernel configuration search

[Bernhard Walle <bwalle@suse.de>]

This patch modifies 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.
