Interesting, I knew of `git add -p` (which I then use to `git commit -m ...`, but it looks like I could add all changes and _then_ decide what to commit. I think I'd still use `add -p` (I like being thorough), but I like that I can add all at once and then make partial commits based on specific change sets.

Thanks for pointing this out, I feel like git is the thing I should know best by now yet I'm missing so much of what it can do. It's great to see others' workflows.
