Subject: how to diff versions of a file
Message-ID: <1c5969370902022100h7c03bbb6h2d9f443f877d89ec@mail.gmail.com>

Hi,
I'm curious if there's a way to diff between 2 arbitrary versions of a file.

For example, how can I see the diff between tree.c on HEAD and from 3
edits (of tree.c) ago?

I can do git log and then manually use commit names to do the diff,
but I'm hoping there's a single command that will let me do that.

Thanks,
Matt
