Sorry, there must be something I am missing :/. I use sed when there are $nl in the messages (not in $me, just in $*). And when I use sed, I avoid characters that can be troublesome for sed. But when there is no need to call sed, I just use $me as is, including with | and \n, as it should not be a problem.
