A potentially much simpler solution occured to me. Could we declare that
Paolo's original patch (the one that started this thread) only applies to
cin? I.e., make the condition this:
if (__sbin == cin->rdbuf() && isatty(0))
Would this work? I'm not sure of all the potential details of reopening cin
-- is it possible for it to get disassociated from fd 0?
