Fast-forward
---
The fast-forward is on branch A. I'd like the git pull to also fast-forward branch B (and branches C,D,Etc.). They're usually by other devs, I don't usually check these, but when I do, I could save an extra command when switching if git just moved the branch head with the data it already has.
git checkout origin/A
Your idea is interesting, didn't know that's useful. Detached head is a bit annoying though.
Thinking on this more I think I'd prefer changing `git checkout/switch <branch>` to automatically use `origin/<branch>` instead (like mook mentions in a sibling comment), rather than changing the `git pull` behavior.
Keeping the local branch refs in place after `git pull` lets you still easily see the local vs remote differences when running `git log`. Changing the behavior of `git checkout` or whatever you use to switch branches to auto fast-forward seems to be a way to have your cake and eat it too, almost.
But, clearly you've thought more on this than I have (having just learned about it lol), what do you think?
