of the partition. Only if the size is 0 should the
special handling of 0 as first argument be triggered.
[This bug caused offset 0 to give C/H/S = 0/0/0 instead of 0/0/1.]
The init_sector0 function needs to decrease the first argument
to the second call to dos() by one to be consistent with the
calls to dos() in change_part().
[This bug caused fdisk -i to create bogus partition tables with
the ending C/H/S value 1 too high. This usually gives S = 1
instead of S = maximum, so the geometry guessing in the slice
code and perhaps in SCSI BIOSes was defeated.]
