ZSH Subversion 1.5/1.6 Tab Completion
Following directions I found here:
http://mkoga.wordpress.com/2008/09/09/zsh-tab-completion-fix-for-subversion-15/
I was finally able to fix the extremely annoying ZSH+SVN tab completion bug.
I have zsh installed via ports so I copied the subversion file to: /opt/local/share/zsh/4.2.7/functions/subversion
Now I finally have tab completion back.. happiness
