9c8e94bc0a ash: fail if 'shift' operand is out of range 
If the numeric argument passed to ash's 'shift' built-in is greater than
'$#' the command performs no operation and exits successfully. It should
return a non-zero exit code instead:

http://pubs.opengroup.org/onlinepubs/9699919799/utilities/V3_chap02.html#shift

This is consistent with bash and hush.
