Whats that movie where a guy on a horse ties a bow at the end...

Whats that movie (probably 70's or early 80's) where a guy on a horse ties a bow at the end and because of the way he ties it, you realise "So it was him" because some dude tied a bow the same way earlier in the movie. Sorry this is all I know about it, a woman goes up to a guy on a horse like a Canadian mountie type dude and he ties the bow for the woman, whom I think has a baby with her.
