    Most if the fixes are due to computing the lengths (and indices) for
    LENSAV.  Apparently the lengths should be log2(N) instead of log(N).
    
    But the fix for c1fm1f.f fixes a genuine bug in the complex fft which
    caused wrong results for non-power of 2 FFT sizes.
    
    Also fixed a couple of typos and incorrect return ier codes.
