Having empty() return TRUE if *all* arguments are empty, and FALSE otherwise
doesn't seem to be as useful (at least from what I've seen in code).
It's less common to see:
if (empty($a) && empty($b) && empty($c)) {}
than:
if (empty($a) || empty($b) || empty($c)) {}
Plus then the semantics wouldn't be inline with isset(), which could be
somewhat confusing to users.
