Homebrew’s `git` not using completion

Question

When using OSX’s git, after I modify a file I can simply do git commit , and that’ll auto complete the file’s name to the one that was modified. Howe

Answer 1

In case anyone else makes my dumb mistake, try brew install git. I was using the git that comes with Xcode and didn't realize that I had never installed Homebrew's git to get the autocompletions.
