Git Plugin for Oh-My-ZSH broken after Updating Git

From the comments, the oh-my-zsh plugin containing the git aliases isn't being sourced.

To do fix this, you can either:

1. Directly source the plugin by adding source ~/.oh-my-zsh/plugins/git/git.plugin.zsh to your ~/.zshrc,
2. Enable the plugin the canonical way: by adding git to the plugins=(...) line in ~/.zshrc: plugins=(git osx ruby). Note: my understanding is that, if you have two lines with plugins=(), the second will overwrite the first - I think (untested) that plugins=($plugins git) allows for enabling of plugins over multiple lines.

To load zsh plugins default format as specified in .zshrc is plugins=(rails git textmate ruby lighthouse). For some reason it was written in this format plugins=(git, lighthouse) separated by comma. Separating just by space and source the .zshrc after saving fixed the issue.
