Whoops...this was a case of the fingers being in gear before the brain
was properly engaged. A 90 degree error is not really "splitting hairs"
but I did mean 180 rather than 90 (i.e. - the lines are mirror images of
each other wrt/ground, one side goes positive as the other side goes
negative). Thanks for pointing that out.
