Code works. It took me a while to understand how to use that FIB function:

L = [0,0,0,0,0]
fib(L, 5)
L

in a cell returns [0,0,0,0,0]. Also why fib instead of FIB?

Finally, the doc from fortran?? was helpful to me. I would suggest not only to copy the fortran code from fortran?? doc but also include how to use it using numpy arrays:

            sage: import numpy
            sage: a = numpy.array(range(10), dtype=float)
            sage: fib(a, 10)
            sage: a
            array([  0.,   1.,   1.,   2.,   3.,   5.,   8.,  13.,  21.,  34.])

Thanks! I added the doctest (and rebased on 8.0.beta2).
