Hello.


My patch for allow recursive variable inderection in arith
and simplify allow $(( )). Originaly from my arith in busybox

Before patch:
$ a=b b=2; echo $((a))
dash: 1: Illegal number: b

After patch:
$ a=b b=2; echo $((a))
2
a=b b="a*2"; echo $((a))
./dash: 4: arithmetic expression: expression recursion loop detected: "a"
