It turns out that the shadow in question is correct, not generated by this
area light.  When I tested the image without the light to see if that shadow
went away, I must have used the wrong options, as the shadow went away <g>.

I'm still interested in general ideas for the "room edge" effect, or the
transition from ambiant to directional light.  I think my idea is OK for
some scenes, but because the illumination isn't an area (it only affects the
shadows) it can cause unwanted highlights too.
