oh-my-zsh alias breaks after_use_maglev hook

In the RVM documentation for ZSH: https://rvm.io/integration/zsh/

There's a section where it says:

> The latest RVM HEAD properly escapes the sourcing '.' so this should no longer be an issue. 

But it looks like the sourcing `.` is not actually escaped in RVM HEAD, so I'm still getting an error. Could the escape be added back in?
