dd2401ed mistake

[gth001]

Mistake: In the 4th panel's output, after the "cursor" doubles it's column position, the squares it rolled over failed to turn blue.

Just experienced this same issue. I see an issue with test #3 (grey should be two columns over to the right by my logic to go past the red and then turn the red to the left to blue) and test #4 (red to the left of the gray column should be blue). Seems like a bug to me.
