    Problem Text
    This test may fail on implementations because the l suffix command
    results are not in the proper order in the expected output.

    There are two distinct problems in this test that need to be
    corrected:

    1) The prompt printed by the G command should not be printed
    in the manner in which an "l" command prints lines. That is,
    the prompt should not contain a dollar sign to denote the end
    of the line. The XCU specification simply says "the line will
    be written" and says nothing about the effect of a possible
    suffix.

    Expecting the prompt to be printed in the manner in which an
    "l" command prints lines is also inconsistent with the
    analogous test for the "n" suffix with the "G" command (test
    409). That test apparently expects the prompt to be printed in
    the style of a simple "p" command. It is illogical to assume
    the "l" suffix will apply to the prompt but the "n" suffix does
    not.

    2) The suite evidently expects the suffix command to be executed
    before the G command has finished completely. We believe this is
    contrary to the XPG4 standard. The expected output for the G
    command and its suffix show a prompt, followed by the same line
    printed again, followed by the output of the command in response
    to the G prompt (.=):

    line 2 changed by the c command$
    line 2 changed by the c command$
    2

    The XCU publication states "... any command ... can be suffixed
    by the letter l, n, or p; in which case ... the command is
    executed and then the new current line will be written as
    described below under the l, n, or p commands."

    The suffix applies to the command "G/he/" and it is this
    command which must be executed before the "l" suffix command
    is executed. We believe the suffix should be executed only
    after the G command has completely finished: after
    all lines matching the regular expression have been exhausted
    and the user-supplied commands for each prompt has been
    executed.

    When these two problems are both corrected, the output from the G
    command only should look like:

    line 2 changed by the c command
    2
    line 2 changed by the c command$
