  sh: Save/restore changed variables in optimized command substitution.
  
  In optimized command substitution, save and restore any variables changed by
  expansions (${var=value} and $((var=assigned))), instead of trying to
  determine if an expansion may cause such changes.
  
  If $! is referenced in optimized command substitution, do not cause jobs to
  be remembered longer.
  
  This fixes $(jobs $!) again, simplifies the man page and shortens the code.
