When you "Install Command Line Tools" from the Github.app, you get symlink'd Git binaries pointing inside the Github.app, like so:
/usr/local/bin/git -> /Applications/GitHub.app/Contents/Resources/git/bin/git
$ git --version
git version 1.8.3.1
Meanwhile OSX/Xcode has it's own flavor:
$ /usr/bin/git --version
git version 1.7.12.4 (Apple Git-37)
And of course the official distro:
/usr/local/git/bin/git --version
git version 1.8.3.2
Is there any appreciable difference in these binaries (beyond the point versions?). I just want the fastest version for a large repo.
