    Problem Text
    This submitter claims the test may fail on implementations that, when
    using the -i option, prompt for existing directories before copying
    any files into them.

    The command line here is 'cp -i -R directory1 directory2',
    and the interactive part is handled by an expect script.
    According to the source comments:

    # NOTE: The standard is silent on the issue of whether or not the
    # directory name will be prompted, and different systems seem to behave
    # differently in this regard. The expect script has a loop to deal with
    # this fact and the consequent indeterminacy of the order of output to
    # expect.

    The comment lies: No such loop is present. We prompt with the directory
    name and the expect script times out. cp_23_1.exp has:

    expect {
    "dircp0232.tmp/dircp0231.tmp/tetcp001.inp" { send "n\r" }
    "dircp0232.tmp/dircp0231.tmp/tetcp002.inp" { send "y\r" }
    }
    expect {
    "dircp0232.tmp/dircp0231.tmp/tetcp001.inp" { send "n\r" }
    "dircp0232.tmp/dircp0231.tmp/tetcp002.inp" { send "y\r" }
    }

    Whereas it should have:

    expect {
    "dircp0232.tmp/dircp0231.tmp/tetcp001.inp" { send "n\r" }
    "dircp0232.tmp/dircp0231.tmp/tetcp002.inp" { send "y\r" }
    "dircp0232.tmp/dircp0231.tmp" { send "y\r" }
    }
    expect {
    "dircp0232.tmp/dircp0231.tmp/tetcp001.inp" { send "n\r" }
    "dircp0232.tmp/dircp0231.tmp/tetcp002.inp" { send "y\r" }
    "dircp0232.tmp/dircp0231.tmp" { send "y\r" }
    }

    or the like.
