directory rename and deletion conflict breaks incremental restore

A user of my Debian packaging of tar notes that an incremental dump
during which a directory is deleted and another directory is renamed to
match the original name of the deleted directory will fail to restore:

  tar: Cannot rename `tartest/dir2' to `tartest/dir1': Directory not empty
  tar: Exiting with failure status due to previous errors

A script for reproducing the problem is available in the bug log at
