title: ZSH auto completion for git takes significant amount of time, can I turn it off or optimize it?
body: <p>Git's tab autocompletion is useful for small projects, but I'm currently working on two big projects that use git and for these it's worse than useless. Whenever I type, say, <code>git add forms&lt;tab&gt;</code>, git takes 20 seconds or more to find the file (in this example, forms.py), and in this timespan I can't do anything else in the terminal. Is there any way to turn off the autocompletion feature, or somehow make it faster?</p>
