  SVN rev 198454 on 2009-10-24 21:20:04Z by jilles
  
  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).
