    All I can see is three posts in current@, that's
    not much of a discussion (or voting).

    I for one, would prefer POSIX compliance. :)

    How about turning this into a warning?

    I believe "loses" is the keyword here. I don't see how this
    would benefit anyone in the long term, sticking with either
    side would be better (but please choose POSIX :).

If you cc me or remove the list(s) completely I'll most likely ignore
your message.    see http://www.eyrie.org./~eagle/faqs/questions.html
