Lines Walk <direction>

This is typically Lines Walk In or Lines Walk Out, and is typically called from facing lines. The ends Pass Thru and step ahead, and then all face the indicated direction and adjust to lines. The centers must resist the temptation to Pass Thru with each other. On a Lines Walk In, the ends' part is a Pass Thru and Ends Bend.
