    Problem Text
    1. if [ $match -eq 0 ] is syntax incorrectly if
    $match is not defined.
    It should be
    if [ "$match" -eq 0 ]
    There are many occurences like this in "grep" test
    suite, this is just an example.

    Test is incorrect: there is no way that the following
    Regular Expression "a\(b\(c\(d\(f\)*\)\)\)\4" would
    match the string "xYzabcdePQRST".

    Here is the reason:
    The back reference expression "\4" should be "\(f\)".
    In the back reference expression "\3", the "\(f\)*"
    can be NULL, but not the trailing "\4".
    So, the correct regular expression would be
    "a\(b\(c\(d\(f*\)*\)\)\)\4" as it will match
    the string "xYzabcdePQRST" as "\4" is NULL.
    The given regular expression "a\(b\(c\(d\(f\)*\)\)\)\4"
    would require at least 1 'f' as the trailing character.

    The previous test case in the same RE table(GA_table_137)
    would prove this point. The regular expression
    "a\(b\)*c\1" would match "acb" as "\(b\)*" is
    expanded into NULL string and "\1" require a single 'b'
    as a matched trailing character.
