Link's position on overworld "Large Map" object is offset by 4

If you have a "Large Map" on a subscreen, on an overworld DMap, Link's position is displayed as 4 to the right of where he really is.

Example: if you're really on screen 53, the map puts the marker at 57.

EDIT: Oh lovely...I thought before I started typing this post, "Don't forget to mark that new bug icon again, dummy"...then went and forgot it, and remembered it RIGHT as I hit the submit button. Bow down to my amazingly awesome short-term memory. 😃
