Revision: 923
Log message:

      Make scanner dependencies soft recursive.  That is, the results of
      a scan become soft dependencies for the next scan.
      
      This will work fairly well for C, addressing bug #423, but it
      is too aggressive for OCaml.  I'll try to address that next.
