Thanks Juan Manuel. I should have tried that first. Hyphenation is the 
same for both /hyphen/​ation (with zero width sp) and 
\emph{hyphen}ation. (Maybe I can nudge Hans Hagen to add some low level 
trickery in context that removes the groups before doing the 
hyphenation... but that's a different story.) Anyway, as Juan Manuel 
shows there can be cases where zero width spaces cause problems.

Denis
