string.atoi and string.atol broken?

[Mike Moum]

I think there may be a bug in string.atoi and string.atol.  Here's some 
output from idle.

s.atoi('4',3) should result in 11

s.atoi('13',4) should result in 31

s.atoi('12',4) should result in 30

s.atoi('8',4) is legitimate, but it generates an error.

Is this a bug, or am I missing something obvious?

TIA,
Mike
