The circumstances in which the parenthesis are mismatched probably
vastly outweigh the circumstances in which the user wants to change
blink-matching-paren-distance.

So, it is arguably more confusing to the average user if the error
message mumbles something about blink-matching-paren-distance.  For
those who care, it's an apropos search away.
