    Problem Summary TIN4C.00010 Test improperly requires user input be read fro standard error.
    Problem Text
    The use of standard error for both prompts and user input by
    more, as required by POSIX.2, may not be possible and another
    file opened on /dev/tty may be required for user input. The
    resolution of IEEE interpretation PASC 1003.2-92 #37 states
    that the relevant text of POSIX.2 is in error.

    Our implementation conforms to the current draft POSIX.2b
    standard, which takes into account the above POSIX
    interpretation. Since this area of the specification is subject
    to change, we request a temporary interpretation allowing our
    existing practice.

    Review Response
    The interpretation referenced does not state the spec is in error.
    It essentially states that the standard is clear and should be followed.

    However, 1003.2b/D11 states

    If standard output is a terminal standard error shall be used to
    read commands from the user. If standard output is a terminal and
    standard error is not readable, and command input is needed, more
    may attempt to obtain user commands fron the controlling terminal
    (e.g., /dev/tty); ...

    Anticipating acceptance of the completely rewritten more specification
    in POSIX 2003.2b/D11 and the eventual alignment of the tests with it
    a temporary interpretation is recommended.
