Ah, you misunderstood the "that sentence is original research" bit-it was about the *original* sentence in the article, not *your* sentence, which indeed sounded more reasonable to me.  
However, just because a word or usage originated in England or in Britain doesn't mean it's used the same way across the English-speaking Commonwealth.  For example, the colloquialisms bloody and mate acquired distinctive connotations in Australia (as opposed to their usage in England) as early as the late 19th century.  U.S. English is not a completely different animal-at least not with respect to Canadian English-and to the extent that it constantly influences pretty much all the other varieties of English.  As for eh, I'd rather go with the literature than with your remarks, which truly qualify as original research in comparison. Jack()
