title: Mercurial to Bitbucket - Subrepository - Repository is unrelated error
body: <p>Here are the steps I've taken to build the repo and subrepos.</p>
  
  <p>Everything is hosted on Bitbucket.</p>
  
  <ol>
  <li>Per best practices, created a skeleton repo to hold all of the subrepos. Cloned to my machine.</li>
  <li>Cloned primary project as subrepo1 (within the mainrepo directory structure).</li>
  <li>Added primary project to mainrepo as a subrepo1.</li>
  <li>Committal of mainrepo works as expected.</li>
  <li>Pushed successfully mainrepo and subrepo1 to Bitbucket.</li>
  <li>Proceeded to clone another subrepo2 to mainrepo directory.</li>
  <li>Added subrepo2 to mainrepo as subrepo2</li>
  <li>Committal of mainrepo works as expected.</li>
  <li>Push of mainrepo results in "Repository is unrrelated" error after is "searching for changes" Error occurs only on the newly added subrepo2.</li>
  </ol>
  
  <p>Here is directory structure:
  mainrepo
  --subrepo1 (main project)
  --subrepo2 (class library)</p>
  
  <p>I've spent countless hours trying to get this working and I must be missing something obvious.</p>
  
  <p>What is causing this error and what am I missing?
  I need to be able to add additional subrepos as the project grows. </p>
