Tim Edwards 5f64c2b3d7 Corrected the "lef" command so that "lef help" works again. 
Corrected the "lef write -hide" command option so that obstructions
outside of the boundary are included in the obstruction list, in
addition to the block inside.  This had previously been done
correctly for use with the "setback" option but would fail only
for setback = 0.
