State-Changed-Why:
    After private mail with Benjamin we believe that this PR
    unfortunately must be kept open. In fact, the behaviour of
    v2 is restored but something is still NOT ok in this area.
    Consider the following run time session for the testcase:
    
    paolo~>a.out
    dddd<NEWLINE>
    sssss<NEWLINE>
    <CTRL-D>
    dddd // echoed
    sssss // echoed
    <CTRL-D>
    paolo~>
    
    That is, after a <NEWLINE> no chars are echoed at all. They
    are all output together upon a first <CTRL-D>, then another
    is needed to end program execution.
    Compare to 3.0.4/STLPort/Icc:
    
    paolo~>a.out
    dddd<NEWLINE>
    dddd  // echoed
    sssss<NEWLINE>
    sssss  // echoed
    <CTRL-D>
    paolo~>
    
    Ciao, Paolo.
