Deref and Into

[Yamakaky]

Did you consider implementing Deref<Target=Path> and Into<PathBuf> instead of the methods into_path() and path() ?

We don't want to implement Deref as it's far too powerful for this situation, but implementing Into should be fine! This is just copied from the very old in-tree implementation and when it was written the conversion traits didn't exist.

Feel free to submit a PR adding the Into impl!
