Presumably you're using 'master'. The "Switched to a new branch" message is an artifact of using git-checkout for the back-end operation, however, what is queued in 'pu' no long uses git-checkout at all, so that message is gone.

I agree with Duy that s/Enter/Prepare/ would be a good idea. I don't think we want to drop the message altogether as Junio suggested since other messages such as "Checking out files:..." and "HEAD is now at...." follow it, thus "Prepare..." provides context indicating that those additional messages apply to the new worktree rather than the current one.

Yep. Again, that fatal error is an artifact from git-checkout being used as the back-end on 'master'. What is queued on 'pu' doesn't fail, however, as Duy notes, the auto-vivication incorrectly kicks in and creates a new branch unnecessarily. That'll have to be fixed in v3.
