    Problem Summary TIN4C.00008 Test fails on implementations which follow historical (1003.2b) behavior.
    Problem Text
    The following incorrectly documents historical practice and is the subject of
    a PASC 1003.2-92 interpretation concerning Ex and Vi :

    POSIX.2 section 5.10.7.2.8 page 525 lines 1395-1396 :
    If file is omitted or results in the current file, the current line
    indicator shall not be changed.

    Historically, the current line is set differently depending on the edit mode
    and arguments given. In this particular case, when the file is omitted or
    results in current file, the current line is set to the first line of the edit
    buffer.

    The historical behaviour is adopted in POSIX.2b draft.11 section
    5.10.7.5.8 page 146 lines 1004-1008 which states

    Otherwise if file is omitted or results in the current pathname:

    Current Line:

    Set to the first line of the edit buffer.

    We believe the test should allow either behavior in anticipation
    of 1003.2b being approved, the XPG spec being realigned with it,
    and the tests needing aligned with the XPG spec.
