title: Send arguments from git push
body: <p>We're using a git post-receive hook to auto-minify our JS and sync our local and remote dev databases.</p>
  
  <p>This is generally desirable, but occasionally not. </p>
  
  <p>Is there anyway to pass an argument to the post-receive hook from git push so this can be disabled when required? </p>
  
  <p>Thanks! </p>
