Just for an extra option to look at, I've been mostly following the branching model described here: http://nvie.com/posts/a-successful-git-branching-model/ and as such have been merging with --no-ff (no fast forward) usually.

I just read this page as I'd accidentally merged a testing branch instead of my release branch with master for deploying (website, master is what is live). The testing branch has two other branches merged to it and totals about six commits.

So to revert the whole commit I just needed one git reset --hard HEAD^ and it reverted the whole merge. Since the merges weren't fast forwarded the merge was a block and one step back is "branch not merged".
