title: SourceTree submodule update - why is it executed?
body: <p>Every time I switch to different branch via SourceTree it executes this command (besides switching branch command)</p>
  
  <pre class="lang-bash prettyprint-override"><code>git -c diff.mnemonicprefix=false -c core.quotepath=false -c credential.helper=sourcetree submodule update --init --recursive 
  </code></pre>
  
  <p>What's the point of it?</p>
