    Problem Text
    The tests may fail on implementations that adhere to POSIX.2b behavior
    where & u are no longer valid, and o O accept a count argument.

    The test assertions listed test an area of POSIX.2 which does not reflect
    historical practice. The draft POSIX.2b standard more closely documents
    the behaviour of historical implementation of Ex and Vi.

    Historically, the list of commands that were handled by the repeat (dot)
    command is !, <, >, A, C, D, I, J, O, P, R, S, X, Y, a, c, d, i, o, p, r,
    s, x, y, ~. The correct behaviour is described in POSIX.2b draft.11 section
    5.35.7.2.33 page 221 lines 3684-3685.

    Our implementation conforms to the draft POSIX.2b standard which mandates
    this historical practice. Since this area of the specification is subject
    to change, we request a temporary interpretation allowing historical practice.
