The famous Austen sentence

The BBC "Pride and Prejudice" miniseries cuts it into two unequal parts. The first: "You are mistaken, Mr. Darcy." The "if you suppose that" is killed, and the next sentence that Ms. Ehle speaks begins with "The mode of your declaration merely spared me any concern I might have felt." The rewriting, I suppose, keeps her breath to swell her song.
