Looks like this fix is incomplete - it works for removed directory, but
not for renamed one (tested on 1.28 with your patch):

$ mkdir /tmp/tar-bug
$ cd /tmp/tar-bug
$ mkdir -p data/dir
$ touch data/dir/file
$ tar cvf full.tar -g snap -C data .
tar: .: Directory is new
tar: ./dir: Directory is new
./
./dir/
./dir/file
$ mv data/dir data/dir2
$ tar cvf incr.tar -g snap -C data .
tar: ./dir2: Directory has been renamed from './dir'
./
./dir2/
$ cp full.tar full2.tar 
$ tar -A incr.tar -f full2.tar -g /dev/null 
$ tar xvpf full2.tar -g /dev/null -C data/
./
tar: Deleting './dir2'
./dir/
./dir/file
./
tar: ./dir: Cannot stat: No such file or directory
./dir2/
tar: ./dir: Cannot stat: No such file or directory
tar: Exiting with failure status due to previous errors
$ echo $?

P.S. Also, I'm not sure is this will be considered a bug, but `tar t` for
concatenated incremental archives show files which won't be unpacked
(which was removed/renamed in concatenated incremental part). This break
code which inspect archives with `tar t` to find out which files will
exists after unpacking this archive.
