Output from the second fsck_msdos on NetBSD/i386 1.6.2 (this was the
machine where i submitted the original PR with 1.5.2).

  # fsck_msdos -y /dev/rvnd0a
  ** /dev/rvnd0a
  ** Phase 1 - Read and Compare FATs
  ** Phase 2 - Check Cluster Chains
  ** Phase 3 - Checking Directories
  /2.TXT starts with free cluster
  Truncate? yes
  /7.TXT starts with free cluster
