title: What is the difference between running git gc with no options vs the --auto option?
body: <p>I was looking through the man pages to find what the default behavior of git gc is when no options are passed and couldn't find anything immediately. I originally was under the assumption that the default when using git gc with no options would be the same as git gc --auto.</p>
  
  <p>Is git gc the same as git gc --auto? If not, what's the difference in behavior?</p>
