Modified Files:
        src/sys/ufs/ffs: ffs_subr.c

Log Message:
clarify comments, especially since ffs_isfreeblock is non-intuitive:
  ffs_isblock:
    check if a block is available
      returns true if all the correponding bits in the free map are 1
     returns false if any corresponding bit in the free map is 0
  ffs_isfreeblock:
    check if a block is completely allocated
      returns true if all the corresponding bits in the free map are 0
      returns false if any corresponding bit in the free map is 1
