title: How to work without access to subrepository in Mercurial
body: <p>There is a project repository A that uses framework subrepository B. Internal team has access to both. Is it possible to limit access to B for external team without breaking possibility to work with A?</p>
  
  <p>Currently it says "abort: response expected (in subrepo ...)" when cancel password entering during cloning.
  Or maybe there is another way for collaboration with different access rules?</p>
  
  <p>Thanks in advance!</p>
