title: Is there an std::string function to append white space up until a given indentation level
body: <p>I amtrying to obtain the following effect:</p>
  
  <pre><code>This is a message            []
  This is a different message  []
  Short                        []
  LOOOOOOOOOOOOOOOOOOOOOOOOOONG[]
  </code></pre>
  
  <p>Is there a way to create a string such that a given parameter always starts at a given indentation level if possible?</p>
  
  <p>e.g <code>string(indentation level, message1, message 2)</code></p>
