Those conditions will never match for any message. Either the unweighted
condition will fail, or "$" will be matched again and again to the opening
putative newline until the score falls to infemum.

Oh, yes, I do. You want to match on messages where the first non-blank
thing in the body is "unsubscribe" at the end of a line, where there are
five lines or fewer in the body?

^.*$ always counts one line too many, so a five-line body will be counted as
six; that's why we need a prejudice of 7.
But if the first non-blank text in the body is "unsubscribe" alone on a line,
is a line count really necessary? True posts that include the word will have
it in the middle of a sentence, such as the preceding one. What you'll find
by specifying a line limit is that unsubscribe requests with long signatures
or attachments at the bottom of a previous message will get through.
