As your email got through to the list, you're bound to get lots of answers unless everybody thinks that (s)he shouldn't inform you because that would be one more answer to all the others. But if everybody skips answering, you won't get an answer at all; so therefore I do send an answer, even though many others will follow the same train of thought and send you an answer, in spite of their original inclination to not send an answer. -w On 13 September 2010 18:19, Gustavo Tenrreiro <gustavo(a)tenrreiro.com&gt; wrote:
