This is very strange. The copy of my message that I received from the mailing list has that corruption, but following the link to the Archive shows the message as I sent it. I just confirmed by looking at the raw content of the message that I received from the list, and the !\n corruption is there in the plain ASCII content (i.e. this is not an HTML formatted message).

Somehow, the message is getting corrupted on its way to some list members and not others.
