This patch totally breaks my usage of the --set-str
argument to "config".

Reverting this patch solves the problem.

Reproduce:
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi-
KBUILD_OUTPUT=build-nomadik nhk8815_defconfig
scripts/config --file build-nomadik/.config --set-str CMDLINE
"root=/dev/ram0 console=ttyAMA1,115200n8 earlyprintk"
sed: -e uttryck #1, tecken 44: flaggan okänd för "s"
sed: -e uttryck #1, tecken 54: flaggan okänd för "s"

Swedish messages meaning "unknown flag for "s""

After reverting the patch these messages no longer appear.

At failure my config file is scratched :-O

Yours,
Linus Walleij
