title: Mercurial: no ~/.hgrc file
body: <p>I am trying to go though <a href="https://confluence.atlassian.com/pages/viewpage.action?pageId=270827678" rel="noreferrer">this tutorial</a> that says:</p>
  
  <hr>
  
  <p><strong>Enable SSH compression for Mercurial</strong></p>
  
  <p>Edit the Mercurial global configuration file (~/.hgrc).
  Add the following line to the UI section:</p>
  
  <p><code>ssh = ssh -C</code></p>
  
  <hr>
  
  <p>But there is no that file in my system. HG of course is installed.</p>
