[pass] [PATCH] zsh-completion: use upstream git completion

[Asbjørn Apeland]

Hi.

I was annoyed that the completion for `pass git` did not include the
whole git completion, for example for `pass git status --<TAB>`.
It was an easy patch for the ZSH completion, as can be see at eg.
https://github.com/RichiH/vcsh/blob/master/_vcsh#L138.

I'd like to request an implementation for BASH's completion system from
someone competent in that.

Would you prefer this complete completion over the existing subset of
git commands?
