Fix for Git Prompt in Homebrew

You could replace /usr/local with brew --prefix and /usr/local/Cellar/git/1.7.12 with brew --prefix git to make it more robust:

if [ -f `brew --prefix`/etc/bash_completion.d/git-completion.bash ]; then
    . `brew --prefix`/etc/bash_completion.d/git-completion.bash
fi

if [ -f `brew --prefix git`/share/git-core/contrib/completion/git-prompt.sh ]; then
    . `brew --prefix git`/share/git-core/contrib/completion/git-prompt.sh
    PS1="\[\e]0;\u@\h: \w\a\]${debian_chroot:+($debian_chroot)}\u@\h:\w \$(__git_ps1 \" (%s)\")$"
fi

Just in case someone stumbles upon this in 2019+

Working code would now be:

if [ -f `brew --prefix`/etc/bash_completion.d/git-completion.bash ]; then
    . `brew --prefix`/etc/bash_completion.d/git-completion.bash
fi

if [ -f `brew --prefix`/etc/bash_completion.d/git-prompt.sh ]; then
    . `brew --prefix`/etc/bash_completion.d/git-prompt.sh
    PS1="\[\e]0;\u@\h: \w\a\]${debian_chroot:+($debian_chroot)}\u@\h:\w \$(__git_ps1 \" (%s)\")$"
fi
