title: How to find out the size of a mercurial repository?
body: <p>So, for example, if there's a mercurial repository <a href="https://code.google.com/p/potentiallyLarge" rel="noreferrer">https://code.google.com/p/potentiallyLarge</a> is there a command which would allow me to find out its size before cloning it?  Something like </p>
  
  <pre><code>hg size https://code.google.com/p/potentiallyLarge
  </code></pre>
  
  <p>Also, is there a command for doing this for subversion repositories?</p>
