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