title: Pull from current origin without explicit typing
body: <p>Is there a shortcut to pull from the current branch without explicit calling it.</p>
  
  <p>E.g. I've checked out a branch: <code>git checkout mybranch</code></p>
  
  <p>To pull from the branch I use <code>git pull origin mybranch</code>. Is it possible to skip the <code>origin mybranch</code> part? The problem is, that our branches have quite long names like <code>b_searchsystem_grid</code>. </p>
  
  <p>Maybe something like <code>git pull origin .</code> (. for current branch).</p>
