Subject: [opkg-utils PATCH] update-alternatives: Installing fails for "["

Insalling packages using update-alternatives will give the following error lines:
sed: -e expression #1, char 41: unterminated address regex
sed: -e expression #1, char 42: unterminated address regex
This is caused by the script update-alternatives.
"[" can not be used directly in sed expression, which should be escaped
in sed expression.
