title: Accidentally created a duplicate branch with different capitalization (Master), how to move it backto master?
body: <p>Whilst moving data from a subbranch back to the <code>master</code> branch, I accidentally created a <code>Master</code> branch (with a capital M).<br />
  The toolset on Windows seems to be oblivious to the difference in capitalization and in my local repo I only have two branches:</p>
  <pre><code> Directory of C:\Users\Me\source\repos\Me\MyProject\.git\logs\refs\remotes\origin
  
  [.]                 [..]                64ThreadsPerBlock   HEAD                master
  </code></pre>
  <p>However in the remote I have three branches:</p>
  <pre><code>64threadsPerBlock
  Master
  master
  </code></pre>
  <p>How do I fix things, so that the remote does not have a <code>Master</code> and it's in sync with the local <code>master</code>?</p>
