docs: If in the list of ignored paths, don't instrument, just coffeeify. We do this here instead of in
  coffee-coverage, as coffee-coverage works on the file system. Since we are getting piped the files,
  we bypass coffee-coverage's filesystem code.
  
  else instrument and coffeeify (which is done by coffee-coverage)
