    awk: Make -F '' and -v FS="" behave the same

    IEEE Std 1003.1-2008 mandates that -F str be treated the same as -v
    FS=str. For a null string, this was not the case. Since awk(1) documents
    that a null string for FS has a specific behavior, make -F '' behave
    consistently with -v FS="".
