title: What is the right ".clang-format" location?
body: <p>I cannot understand the following text from the clang-format manual:</p>
  
  <pre><code>.clang-format file located in one of the parent
  directories of the source file (or current
  directory for stdin).
  </code></pre>
  
  <p>What does "current directory for stdin" mean? Is it the current directory or the stdin?</p>
  
  <p>Is it possible to specify the .clang-format location by a full path?</p>
