¿Qué significa el guión independiente (-) de Curl?

¿Qué significa el guión independiente (entre -C& -O) en este comando?

curl -C - -O http://www.intersil.com/content/dam/Intersil/documents/fn67/fn6742.pdf

FWIW- Estoy siguiendo un tutorialaquí.

-C -determina automáticamente cómo reanudar la transferencia, basándose en los archivos de entrada y salida.

Deman curl(tenga en cuenta el segundo párrafo):

   -C/--continue-at <offset>
          Continue/Resume a previous file transfer at the  given  offset.
          The  given  offset  is  the  exact number of bytes that will be
          skipped, counting from the beginning of the source file  before
          it  is  transferred  to the destination.  If used with uploads,
          the FTP server command SIZE will not be used by curl.

          Use "-C -" to tell curl to automatically find out where/how  to
          resume  the transfer. It then uses the given output/input files
          to figure that out.

          If this option is used several times,  the  last  one  will  be
          used.
