It would seem that [this line](https://github.com/nodegit/nodegit/blob/master/lib/commit.js#L176)...\n\n``` js\nreturn thisTree.diff(parentTree);\n```\n\nshould in fact be \n\n``` js\nreturn parentTree(thisTree);\n```\n\nMostly because, in my expectation, getDiff would give me the changes made in that commit from the previous, **not** the changes required to undo the commit. \n\nBasically, I believe the current method is performing something like\n\n``` bash\ngit diff sha..parent\n```\n\nwhen I would expect\n\n``` bash\ngit diff parent..sha\n```\n\nAm I reading this right, or am I just going crazy? If I'm right, I can put in a PR to fix, I just wanted to make sure I'm understanding before I put in the change.\n","author":{"url":"https://github.com/orderedlist","@type":"Person","name":"orderedlist"},"datePublished":"2015-01-26T22:00:33.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":6},"url":"https://github.com/368/nodegit/issues/368"}
