The same that using "/bin/su -" gains you: a bit more of defence against
someone doing nasty things to your environment. Note the use of "a bit", as
in "a small ammount".
If you are going to use "-" for this reason, do the full thing and run
/bin/su - and not su -. You don't want to trust $PATH either, after all.
