  merge working like union

It seems that the merge{} structure doesn't elliminate internal surfaces as
it should; see this scene:

camera {
 location -10*z
 look_at z
}
merge {
 sphere {x,2}
 sphere {-x,2}
 pigment {rgbt .9}
 finish {ambient 1}
}

Manually constructing the merge doesn't work either:

intersection {
 sphere {x,2 inverse}
 sphere {-x,2 inverse}
 pigment {rgbt .9}
 finish {ambient 1}
 inverse
}

Although if you remove the final 'inverse,' you do get the inverse of the
result you want.
