Jilles Tjoelker 64254a667a sh: Exempt $@ and $* from set -u
This seems more useful and will likely be in the next POSIX standard.

Also document more precisely in the man page what set -u does (note that
$@, $* and $! are the only special parameters that can ever be unset, all
the others are always set, although they may be empty).
