title: tar files including directory without siblings
body: <p>I have following file structure</p>
  
  <pre><code>.
  ├── doc1.pdf
  ├── doc2.pdf
  └── images
      ├── img1.jpg
      └── img2.jpg
  </code></pre>
  
  <p>I would like to tar images directory preserving parent <code>images</code> (without full path to it). What is more i would like skip other documents in directory (doc1, doc2) Currently I use:</p>
  
  <pre><code>tar -cf /sth_dir/images.tar -C /images/ . --exclude="doc*"
  </code></pre>
  
  <p>but  i would like to not use <code>--exclude</code> because additional files, with different names might be added there. </p>
