Hmmm,
On my linux (debian) system, su shows this:

jason at foobar[3:07pm](205)> su -l foobar
su: invalid option -- l
Usage: su [OPTS] [-] [username [ARGS]]
        -       make this a login shell
        -c, --command=<command>
                pass command to the invoked shell using its -c
                option
       -m, -p, --preserve-environment
                do not reset environment variables, and keep the
                same shell
       -s, --shell=<shell>
                use shell instead of the default in /etc/passwd


Cheers,
jason
