title: git push vs git push origin <branchname>
body: <p>I'm quite new to Git.</p>
  
  <p>I'm creating a branch and then want to push it to <code>origin</code>.</p>
  
  <p>I think that simply issuing <code>git push</code> (while standing on my branch) should be sufficient.</p>
  
  <p>Is it possible/reasonable to do that (by specifying push.default simple)?</p>
