title: Using the pre-commit hook to clean code
body: <p>Is it good form to scrub development code from my source files during a  pre-commit hook?</p>
  
  <p>For example, I have code that is calling xdebug_break() and I want to remove the calls to that function from any files that have it before committing my code to the repository.  I would rather not check for the function before calling it because I am the only one that wants that function call there.</p>
