[Numpy-discussion] Possible typo in numpy.dft.fft docstring

Part of the fft function's docstring currently reads:
"...
The packing of the result is "standard": If A = fft(a, n), then A[0]
contains the zero-frequency term, A[1:n/2+1] contains the
positive-frequency terms, and A[n/2+1:] contains the negative-frequency
terms, in order of decreasingly negative frequency. So for an 8-point
transform, the frequencies of the result are [ 0, 1, 2, 3, 4, -3, -2, -1].
..."
Shouldn't the frequency arrangement in the last sentence be
[0, 1, 2, 3, -4, -3, -2, -1]
and not
[ 0, 1, 2, 3, 4, -3, -2, -1]
?
