The output of the

command is supposed to be bit for bit compatible to the original Unix

command, because its output is processed by other programs like CGI scripts, that should not be broken. Therefore it will always output 8 lines, even if only 7 contain data. This extra blank line also appears with the original

command, at least on Solaris 8

Not all options are compatible and using them in different orders will give varying results.
