I withdraw the suggestion. Since the default .ss 12 12 has the same
effect at a mid-line "sentence space" as copying the double space, I
had not realized that AI tinkers with the width of such spaces as well
as end-of-line sentence spaces. Thus double spaces do not harm
documents typeset with sentence-space 0.
