int-str: 0x bug.
* lib.c (int_str): The problem here is that we are recognizing
and skipping the 0x prefix for all bases. So for instance
(int-str "0x123") produces 123. The correct requirement, and
the intent of the code, is that the C conventions are only
honored if the base is specified as the character #\c. In any
other base, including omitted base defaulting to 10, a leading
zero is just a leading zero, and 0x is a zero followed by the
junk character x. Therefore, if we have any valid base that
isn't #\c, and 0x has been seen, we must return zero. We must
not do this only in the base 16 case.
* tests/016/conv.tl: New file.
