OS X

Create/add/replace your ~/.bash_profile with the contents from above. The /usr/local/etc/bash_completion.d/git-completion.bash script is installed with git when you install git with brew (http://mxcl.github.com/homebrew/).

Linux

Using the above in your ~/.bash_profile should work, but you'll need to install the git-completion.bash script from https://github.com/git/git/blob/master/contrib/completion/git-completion.bash.

Windows

I haven't tested it, but following the Linux instructions in Cygwin should/might work.
