    Problem Text
    A MSF is requested because '.' does not repeat the 'p' commands.

    References TSD4C.00091 and MSF4C.00006.

    TSD4C.00091 covers two of the above error conditions, however,
    the Consultant recommended that we apply for a MSF based on
    MSF4C.00006 for the "p" or "P" case.

    To reitterate:

    The test in question verifies the assertion:
    When [count] . is entered in command mode, then vi repeats the last
    command that changed the buffer and uses count as the number of
    iterations of the command being repeated. (Default 1 when count not
    specified) The values of current line and column are set as specified by
    the command which is repeated.
    TESTING REQUIREMENT:
    Test for each of the buffer changing commands !, &, <, >, ~,
    a, A, c, C, d, D, i, I, J, o, O, p, P, r, R, s, S, u, U, x and X.

    There is an error in the existing test (recognized by waiver
    #TSD4C.00091) in that some of the expected output files are incorrect.
    However, on our implementation the assertion fails for the "p" and "P"
    commands independently of this error (subtest number 7 in the
    assertion test). This behavior (a failure to repeat a "p" or "P") is
    longstanding; according to Keith Bostic, it is the historical behavior
    of vi. Nevertheless, he views it as a bug, as do POSIX.2-1990, XPG4
    Issue 2, and (draft) POSIX.2b.

    We request a waiver on the grounds that this is a Minor System Fault.
    In support of this request we wish to point out that:
    (a) The current test suite, because of its own bug, does not exhibit
    this failure.
    (b) This is the historical behavior of the vi utility.
    (c) A workaround (using "p" or "P" instead of ".") is always available
    to the user.
