Re: [Bug-tar] Tar hangs (blocks?) on existing file when extracting with `--skip-old-files` and `--xattrs`.

Could do with a test case that fails.  This works with tar 1.29-1 on
Arch Linux.

    $ (cd src && tar --xattrs -cf - .) |
    > (cd dest && tar --xattrs -xvf -)
    ./
    ./foo
    $
    $ touch src/bar
    $ (cd src && tar --xattrs -cf - .) |
    > (cd dest && tar --xattrs --skip-old-files -xvf -)
    ./
    tar: .: skipping existing file
    ./foo
    tar: ./foo: skipping existing file
    ./bar
    $
    $ (cd src && tar --xattrs -cf - .) |
    > (cd dest && tar --xattrs --skip-old-files -xvf -)
    ./
    tar: .: skipping existing file
    ./foo
    tar: ./foo: skipping existing file
    ./bar
    tar: ./bar: skipping existing file
    $
