    Problem Text
    This test will fail on systems where the circumflex does not anchor
    subexpressions to the beginning of a string.

    Case 1 - BRE: '\(^*ab\)' S: '*ab' V: 1 M: 0

    Is doing this command:

    sed -n -e s/\(^*ab\)/MATCH/p sed_in_149_1

    sed_in_149_1 contains:

    12345
    *ab
    67890

    The test is expecting '\(^*ab\)' to match the '*ab' in the file,
    and be replaced by 'MATCH'. If subexpression anchoring is not
    supported, the BRE ins interpreted as "0 or more occurences of
    '^' followed by 'a' followed by 'b'". This matches 'ab', which
    results in '*MATCH' being output.


    Case 2 - BRE: '\(^*ab\)' S: '^*ab' V: 1 M: 0

    Is doing this command:

    sed -n -e s/\(^*ab\)/MATCH/p sed_in_149_2

    sed_in_149_2 contains:

    12345
    ^*ab
    67890

    The test expects no match, but does in fact match 'ab', resulting
    in '^*MATCH'.
