If you don't run checkout on file paths, how do you undo changes to specific files that you haven't committed yet? Like you've edited but not committed <foo>, <bar>, and <baz>. You realize your edits to <bar> are a mistake. I'd just run `git checkout <bar>` to revert those changes, what do you do?

It is also really useful when you realize you want <bar> to be the version from a commit two weeks ago. I guess you could always switch to the branch 2 weeks ago, copy the file to /tmp/, switch back, and copy the file into place, but `git checkout c23a99b -- <bar>` is so quick and easy. Or does this example not fall under the "dont run checkout on a path" since it is taking a treeish first before the path?
