title: In the context of git (and diff), what is a "hunk"
body: <p>I was looking for a definition of "hunk" while reading some git documentation.  </p>
  
  <p>I know it means a description of the difference between two files and that it has a well defined format, but I couldn't call to mind a succinct definition.  </p>
  
  <p>I tried searching with google, but there were a lot of somewhat spurious hits.  </p>
