title: Github single pull request for changes to multiple repositories?
body: <p>Is it possible (or even smart) to pack changes for multiple repositories into a single pull request on Github? Or would it be better to make two separate pull requests?</p>
  
  <p>In my specific case, I am adding a new feature to Paris, the simple Active Record implementation built on top of Idiorm. But the change in Paris also requires a change in Idiorm. Idiorm and Paris are from the same author but live in different repositories.</p>
  
  <p>Can I (and should I) make a single pull request? Or do I need to make two, and then comment in the second pull request that it won't work unless the first changeset has been merged on the other repository?</p>
