    Problem Text
    The tests may fail on implementations that adhere to historic practice
    such that the command "ye" yanks up to and including the position
    described by the "e" motion command. Although POSIX.2 interpretation
    requests 64 and 75 reaffirm the behavior, the POSIX.2b draft reinstates
    the historic behavior.

    The test assertions listed test an area of POSIX.2 which the POSIX.2
    interpretation committe has determined to be in error (see IEEE
    interpretations PASC 1003.2-92 #64, question #35, 36, 37, 38, 53, 54,
    55; PASC 1003.2-92 #78, question #15).

    The regions marked out by motion commands when supplied to commands
    requiring a motion argument (c, d, y, >, and <) is described in POSIX.2b
    draft.11 section 5.35.7.2 for each motion command in question. In most
    instances, historical regions have been maintained, however the word, sentence,
    paragraph, and section motion commands have been normalised in their handling
    of empty lines and the regions they spanned.

    Our implementation conforms to the draft POSIX.2b standard, which
    regularizes the behaviour of Ex/Vi in this area. Since this area of
    POSIX.2 is subject to change, we request a temporary interpretation
    allowing the behaviour described by POSIX.2b.
