(string->number "08") => 8 would be consistent with C

I just tried scanf of 08, 09, 010 in C, and got 8, 9, 10.

However, C is not always consistent with itself; 08 cannot be used as a 
constant:
foo.c:9:19: invalid digit "8" in octal constant

Since Tim's unit tests already include:
(equal? (string->number "010") 10)

I think (string->number string-value) in the absence of radix should 
assume a radix of 10.
