[Bug-tar] tar doesn't honor --exclude-caches with --listed-incremental

[Dan H.]

Well, I guess a little shell transcript shows what I mean.

address@hidden:~$ ls test
CACHEDIR.TAG  foo
address@hidden:~$ cat test/CACHEDIR.TAG
Signature: 8a477f597d28d172789f06886806bc55
address@hidden:~$ tar -cvf test.tar --exclude-caches test
test/
tar: test/: contains a cache directory tag; not dumped
address@hidden:~$ tar -cvf test.tar --exclude-caches \
   --listed-incremental test.snar test
test/
test/CACHEDIR.TAG
test/foo
address@hidden:~$

Is this a bug or some feature that I can't find in the docs? Apart from
that I'm with the crowd that thinks that the CACHEDIR.TAG file itself
should be restored when a backup tarball is extracted.

Thanks,
