Title: repository: add a getter and remove function for git's prepared message

The 'git revert/cherry-pick/merge -n' commands leave .git/MERGE_MSG
behind so that git-commit can find it. As we don't yet support these
operations, users who are shelling out to let git perform these
operations haven't had a convenient way to get this message.

These functions allow the user to retrieve the message and remove it
when she's created the commit.

I screwed up and accidentally closed issue #192 in such a way that I can't re-open it. This is the simpler method I talk about there.
