  21 # The bug occurs when extracting from a tarfile a directory when the directory
  22 # already exists and the version in the tarfile has more permissive
  23 # permissions than your umask.  In this case, the permissions of the
  24 # existing directory will toggle between the version which complies with
  25 # your umask (which would be correct, without -p) and the version from the
  26 # tarfile.
