throughout the bsdconfig(8) code. While we're here, add an explicit argument to lvalue-seeking invocations of "return" that previously had no argument. Also, consolidate a single instance of double-newline and remove some comments that are no longer required (given increased readability with new exit codes). Approved by: re (glebius)
