    Problem Text
    This IR claims that an invalid job identifier is being specified.

    Reason for failure:

    This testcase fails as it expects the operand (pid) to be a
    shell script.

    As per the POSIX 1003.2 standards [Volume-1, Line no 10954-10963]
    the operand (pid) specified should be an unsigned integer, of a job
    control ID on systems supporting job control option.

    We recommend this request be refused.

    We believe the test is correct.

    The wait specification allows two variations of the pid operand (page
    803 in the XCU spec, or section 4.70.4 of POSIX.2),

    1. The unsigned decimal integer process ID of a command, for
    which the utility is to wait for the termination.

    2. A job control job ID (see the XBD specification, Chapter 2,
    Glossary) that identifies a background process group to be
    waited for. The job control job ID notation is applicable
    only for invocations of wait in the current shell execution
    environment; see Section 2.12 on page 96. The exit status of
    wait is determined by the last command in the pipeline.

    The shell scripts referred to (%./wait_10_prog1, %?10_prog2) are
    legitimate job control job IDs. The XBD, page 19, or POSIX.2 section
    2.2.2.94, defines job control job ID formats allowed,

    Job Control Job ID Meaning

    %% Current job
    %+ Current job
    %- Previous job
    %n Job number n
    %string Job whose command begins with string
    %?string Job whose command contains string

    In this case,

    %./wait_10_prog1
    %?10_prog2

    are both allowed job control job IDs that be passed to the wait
    utility. Shell scripts are considered commands as described in
    section 2.9 of the XCU or section 3.9 in POSIX.2
