body: <p>How to submit a pull request from an existing locally-cloned repo?</p>
  
  <p>Often,  I want to look at some libraries source code from github, so I clone it. Later, I discover some issue with the code and raise it on a mailing list, often in passing. The library author says "nice find, can you send a pull request?".</p>
  
  <p>And the answer is "not that easily". I haven't forked the repo yet, Ive cloned it. And there doesn't seem a way I can find to submit a pull request from a cloned repo?</p>
  
  <p>If this limit is true, it feels like the sensible reaction is to fork anything and everything you ever look at, just so that if you ever might want to contribute, you can. And that fills up your github account with many inactive forks. </p>
  
  <p>Doesn't seem a lot of talk about this issue - am I the only person whom this problem affects?</p>
