If non-nil do smart filling of addressee header lines.
Smart filling means breaking long lines at appropriate points and making continuation lines. Despite the function name, it includes To:, Cc:, Bcc: (and their Resent-* forms), as well as From: and Reply-To: (though they seldom need it). If nil, the lines are left as-is. The filling is done after mail address alias expansion.
