Fix the Rectangular Pattern feature to allow a sketch block to be used as the "Direction"

[nannerdw]

I have a sketch consisting of three lines in a "U" shape.

I can select all three of those lines as the "Direction" for a Rectangular pattern, and the pattern will follow entire the U-shaped path.

However, if that U-shape is inside a sketch block, then I can only select one of those three lines as the "Direction".
