$ git checkout --track origin/next
Exactly. A branch called 'next', that tracks origin's branch 'next'.
I like this.
An explicit --track request from the command line (as opposed to happening
to have "branch.autosetupmerge" configuration) is a very good cue that
what the user wants to do is not to take a peek on a detached HEAD but a
more permanent playpen created.
