I’ve been rewriting _git for a while now.  I’ve updated all the Main
Porcelain Commands.  I’m currently stuck on something as unimportant
as git-config, but I want to get everything right and I’m doing it all
in man page order.  I’ll hopefully have a delayed Christmas gift for
you all at the beginning of 2011.  I’ll take a look at your changes
and integrate them if they are still applicable.

My main problem right now is that I’m working off of the Debian Zsh
Git repository where I don’t have write permissions.  I’d like to set
up a Zsh Git repository at GitHub so that I can more easily distribute
my changes, but I haven’t had time to look into setting this up.
Perhaps someone can explain how you set up a CVS-to-Git mirror on
GitHub?

I’ll also try to set up zstyles to the effect of allowing you to
disable potentially costly completions.
