As per ECMA-262 definition (see p. 105, section 15.5.4.15), if the second parameter of substring is "undefined", it should return the substring to the end of the string.
For example:
var a;
var b = '012345'.subtring( 3 );
// b == '345'
In the above example we have b == '012' with Firefox. All other browsers (IE, Safari and Opera) set it to '345'.
Reproducible: Always
