But in this case, one would have to ask "to what purpose". It's essentially just imposing one's personal taste, rather like restricting numbers to disallow a leading "+" sign. You can tell when someone is committed to standards by the fact that they conform even when it goes against their personal taste. Michael Kay Saxonica
