I just noticed that the output of disklabel(8) on SNAP-950412 reports the
number of partitions to be one more than it displays.  The main reason I
noticed it was that when editing the label, and setting the number to the
actual number:

3 partitions:
#        size   offset    fstype   [fsize bsize bps/cpg]
  a:   164538      198    4.2BSD      512  4096    16   # (Cyl.    1 - 831)
  c:   164538      198    unused        0     0         # (Cyl.    1 - 831)
  d:   164736        0    unused        0     0         # (Cyl.    0 - 831)


disklabel would say:

Warning, unused partition d: size 164736 offset 0


and sure enough running disklabel again reports:

3 partitions:
#        size   offset    fstype   [fsize bsize bps/cpg]
  a:   164538      198    4.2BSD      512  4096    16   # (Cyl.    1 - 831)
  c:   164538      198    unused        0     0         # (Cyl.    1 - 831)


If I tell it I've got 4 partitions, then the 3 get written to the label
correctly.
