    Well, is a space followed by a diacritic actually a space, or is it the
    same code point reused or overloaded "By convention" (to quote the
    standard) for a logically distinct purpose? Some of the discussions here
    have implied the latter. Either way, the best clarification would be to
    add a character whose explicit function is to form non-spacing variants
    of diacritics.
