Yes you are. I know what the possible side-effects are, and I am
knowingly avoiding them, it works perfectly fine, it's just not neat.

No I'm not.

I have, I've helped to write it. In fact, I'm probably the main
contributor at this point. In fact, I'm aware of at least one bug for
which I haven't managed to send the patch for.

I already discussed the shortcomings in this list:
http://thread.gmane.org/gmane.comp.shells.zsh.devel/22454/focus=22475

Basically it's dead slow, and Nikolai Weibull is opposed to make it usable.

BTW. My zsh wrapper for git.git bash's completion is the official way
git recommends completion for zsh, and it's distributed accordingly:
https://git.kernel.org/cgit/git/git.git/tree/contrib/completion/git-completion.zsh

And the folks of 'oh-my-zsh' are also thrilled of finally having
completion that is not slow as a snail:

Cheers.
