Subject: [PATCH] scripts/config: allow setting a string which value contains a colon

A bug in script `config' prevented from modifying an existing variable's
value to a string that contains a colon ':'.  The reason behind it is that
colons are used as a separator in `sed' commands that script `config'
relies on.

Escape colons in `sed' commands to allow values containing colons.
