Comment(by rgommers):

 For fft a choice (fft nisn't normalized, ifft is normalized by 1/N) is
 made and that choice is documented. No choice is given to the user,
 because multiplying the output by a constant factor is just as easy as
 specifying normalization with a keyword.

 The normalization here seems to be more than multiplying by a constant
 though, so it may be good to implement.  For backwards compatibility the
 default should be normalize=False I think.
