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