title: ST3: insert same character till end of line
body: <p>Is there a way to insert the same character till the end of the line in Sublime Text 3? I would like to use this feature to structure my code by comments.</p>
  
  <p>E.g. when coding in R I may want to have a comment "Load file" where the dashes go to the 80th column.</p>
  
  <pre><code># Load file --------------------------------------------------------------------
  </code></pre>
  
  <p>In other cases the comment may be longer, so the number of characters inserted should be adjusted accordingly.</p>
