title: What is the canonical way to reference a git repository and branch
body: <p>I think I saw somewhere that <code>repository#branch</code> was legit, but not sure.  Have done a bit of searching for this, it's one of those things that's a little hard to find good search keywords for.  "git repository branch canonical" hasn't returned much.</p>
  
  <p>The reason I ask is just simply to know the best way to refer to repository branches amongst my development team.  It's kind of a trivial question, I know, but I'm just curious about it.  I regularly work with several repositories and several branches within each so it's something that I need to use a lot.</p>
