   4:  * Badsect takes a list of file-system relative sector numbers
   5:  * and makes files containing the blocks of which these sectors are a part.
   6:  * It can be used to contain sectors which have problems if these sectors
   7:  * are not part of the bad file for the pack (see bad144).  For instance,
   8:  * this program can be used if the driver for the file system in question
   9:  * does not support bad block forwarding.
