And thanks for the explanation, Nick. At least my approach to set the value would not work at all without an explicit call to org-set-emph-re, since it relied on the variable being already defined. It might be of minor interest, anyway, I've attached a patch-suggestion that would clearify the usage sufficiently, at least for me...
