Subject[PATCH 4.9 09/18] scripts/config: allow colons in option strings for sed
Date
From: Jeremie Francois (on alpha) <jeremie.francois@gmail.com>

[ Upstream commit e461bc9f9ab105637b86065d24b0b83f182d477c ]

Sed broke on some strings as it used colon as a separator.
I made it more robust by using \001, which is legit POSIX AFAIK.

E.g. ./config --set-str CONFIG_USBNET_DEVADDR "de:ad:be:ef:00:01"
failed with: sed: -e expression #1, char 55: unknown option to `s'
