[PATCH] Many missing options for git-diff zsh completion

[Matthieu Moy <Matthieu.Moy@xxxxxxx>]

Hi,

git-diff has a lot more options that the latest _git file has.

Here's a patch that adds them (feel free to remove a few of them if
you do not believe they're common enough, but the list seems fine as
it is).

Please, Cc me in your replies, I'm not a list subscriber.

Thanks,
