no, but i must admit that it's kind of a border case ... i'll fix it but
also wonder if *no* visual rule showing up is intended (i would then
also expect an engine to show a rule .. could be an interesting new
(luametatex) option as it saves kerns in some cases)
see Wolfgangs mail for a better solution using kerns
