title: When I export mercurial to git, why is the result so large?
body: <p>I have an old mercurial repository that I am exporting to git using hg-fast-export.  It is 115MB.  When I run hg-fast-export <a href="https://stackoverflow.com/questions/16037787/convert-mercurial-project-to-git">as described here</a>, the resulting git repository is 663M.  Any idea why that would be?  </p>
