How do I find the differences between two git remotes
===

In my local copy of our svn repo (created using git-svn), I have multiple remotes representing a series of releases of our project: remotes/tags/release1 remotes/tags/release2 etc. How can I use git to show me the changed revisions and/or the diffs between releaseN and releaseN-1?

I have tried `git diff remotes/tags/releaseN-1 remotes/tags/releaseN`  and `git log remotes/tags/releaseN-1 remotes/tags/releaseN`, but both of these just give me the "unknown revision or path not in the working tree" error message.
