title: GitHub: Linking to an issue from a wiki page
body: <p>On GitHub, is there a simple way to reference an issue (eg: <code>#1234</code>) from within a markdown file such that it is displayed as a hyperlink?</p>
  
  <p>I don't want to write out the full form each time, as in:</p>
  
  <pre><code>[#1234](//github.com/user/project/issues/1234)
  </code></pre>
  
  <p>In commit messages, issue numbers are automatically hyperlinked. Can this happen in wiki documents too?</p>
  
  <p>(This is not a duplicate of <a href="https://stackoverflow.com/questions/12472682/github-link-from-issue-to-wiki">this question</a> which is simply asking about markdown hyperlink syntax.)</p>
