[BusyBox] bug#1283: lash argument numbers are shifted

[Dan Fandrich]

Package: busybox
Version: 0.60.5

Executing the following program 'args':

#!./lash
echo 0:$1 1:$1 2:$2 3:$3

like this:

./args a b c

in a directory containing a symbolic link lash -> busybox, results in the
output:

0:./lash 1:./args 2:a 3:b

Arguments numbers >= 1 are one higher than they should be. Replacing the
first line of the script with #!./ash or #!/bin/bash results in the
expected output:

0:./args 1:a 2:b 3:c
