I regularly see the phrase "all Xs are Ys, but not all Ys are Xs" in teaching material. Even material for children!
I have to re-read it every time. I very much prefer "Y is a more general category than X" or "X is a subset of Y".
Do people find this phrasing helpful, or is it poor pedagogy?

* Better handling of nesting changes, based on autochrome. This fixes some nasty corner cases (Python screenshot) and gives nicer results in general (Scala screenshot).
* Better handling of large files, even multi-megabyte!
I'm not convinced that offering the staging area is a good default for git.
It's an abstraction that newcomers have to learn before their first commit. Subversion style "commit every tracked file" isn't as pretty (`git add` is general) but it's the common case.
