How do I get the literal ctrl-M into the bracket expression?
Literal ctrl-M is probably not what you want anyway, because during the SMTP transaction lines are delimited by "\r\n" and by the time procmail gets the message it probably has been rewritten to have only "\n" (which is ctrl-J).
Instead you should make use of another procmail oddity, which is that the $ [end-of-line] marker actually matches a newline character rather than matching a zero-width boundary as it does in other regex engines like perl's.
So if you use ([^;]|($))+ you'll match one or more non-semicolon or newline characters. The extra parens around ($) are an idiom to distinguish it from introducing a variable expansion.
