Re: cdgit: cd relative to git workdir root

Hi,

I frequently have the need to cd back to the root of the current git workdir 
and created to alias for this:

git alias root = rev-parse --show-toplevel

shell alias cdgit = cd $(git root)

Maybe somebody likes this.

I do, and I was about to copy it into my own config when I discovered
that I'd already done this 4 years ago and totally forgotten about it :)

Now it would be cool, to have an alias to cd into a specific subdir of the git 
worktree and have zsh (or bash) auto completion for this like

git clone git://git.kernel.org/pub/scm/git/git.git
cd git/gitweb/static/js/lib (just to be somewhere deep)
cdgit con<tab>/com<tab> (becomes: cdgit contrib/completion)

Somebody with zsh/bash skills who already did this?

I hadn't done this before today, but it's easy in zsh:

Of course, _gitcd needs to be somewhere on your $fpath so it can be
autoloaded.
