    Problem Text
    Test exits with a non-zero exit status.

    Test #48 creates the following command and input files

    |> # Create command file ed_in_48_1
    |> cat << \VSC-EOF > ed_in_48_1
    |> G/Greek/
    |>
    |> Q
    |> VSC-EOF
    |>
    |> # Create input data file ed_in_48_2
    |> cat << \VSC-EOF > ed_in_48_2
    |> Greek Line 1
    |> Greek Line 2
    |> George Bernard Shaw
    |> VSC-EOF
    |> ed < ed_in_48_1 ed_in_48_2 > $CT_STDOUT 2> $CT_STDERR

    As you can see, it creates a file with _two_ instances
    of lines matching the pattern /Greek/, but then runs
    a 'G' (globally, one at a time) command, feeding the
    G command only _one_ empty line. The "ed" command
    complains when the "Q" command is submitted to the
    "G" command while "G" is stopped at the second /Greek/
    line.

    We believe the test should either have a second blank line in
    the command file

    |> # Create command file ed_in_48_1
    |> cat << \VSC-EOF > ed_in_48_1
    |> G/Greek/
    |>
    |>
    |> Q
    |> VSC-EOF

    or else only have one /Greek/ line in the input file

    |> # Create input data file ed_in_48_2
    |> cat << \VSC-EOF > ed_in_48_2
    |> Greek Line 1
    |> George Bernard Shaw
    |> VSC-EOF

    VSC4.1.4/vsc/tset/POSIX.cmd/ed/ed_01.ex:tp49()

    Test 49 fails in almost exactly the way just reported for test 48.
    It uses the same input file to test that "V/George/" selects and
    prints the same lines as the "G/Greek/" command did in test 48.

    We recommend this request be refused.

    The ed spec states

    In the G command, the first step is to mark every line that
    matches the given RE. Then, for every such line, that line will
    be written, the current line number will be set to the address of
    that line, and any one command (other than one of the a, c, i, g,
    G, v and V commands) can be input and will be executed. A
    newline character acts as a null command (causing no action to be
    taken on the current line); an & causes the reexecution of the


    We read this as specifying that the command

    G/Greek/

    will mark the 2 lines in the input file containing the string, Greek.

    Then the first marked line

    Greek Line 1

    will be displayed.

    The next command is a newline which the spec says will cause no
    action. So the next marked line

    Greek Line 2

    will be displayed.

    The next command is Q. Since this is not one of the commands disallowed
    above (a, c, i, g, G, v and V commands) it should be executed without
    error. At that point ed should exit with a 0 exit status.

    Essentially the same logic holds true for test 49.
