PROBLEM:  (QAR 62880)    (Patch ID: OSF410-405504)
********
Without this patch, the file command erroneously reports 0 for the bit
and Hz fields when you specify a WAV audio file as input.  For example:

  > file SQUISH.WAV
  SQUISH.WAV:     Microsoft RIFF - WAVE format 0 bit Mono 0 Hz

This patch corrects the file command behavior, so that it outputs actual

values in the bit and Hz fields.  For example:

  > file SQUISH.WAV
  SQUISH.WAV:     Microsoft RIFF - WAVE format 8 bit Mono 11025 Hz
