normalizing clipping 32bit wav files?

Hi list,

I have a 32bit wav file in 0x3 => WAVE_FORMAT_IEEE_FLOAT with samples
outside of -1 and 1 which will be clipped at playback. 

Using 
 sox in.wav out.wav norm -1 
will clip these files as well instead of leaving the original waveform
intact. Audacity is able to do this.

Is this intentional, if not is this known, should I be filing a bug
report?

Thanks! Peter
