I think this '%s' is just confusing, how is repeating the name of the
branch at the user (which we're about to mention in the example command)
helpful?
Shouldn't we just omit it, or reword this to e.g.:
If you'd like the '%s' branch to be a worktree containing a
new....

Missing the usual:
"Turn this message off by running\n"
"\"git config advice.worktreeAddOrphan false\""
blurb.
Also, should we really add twe newlines at the end? I see some other API
users that don't add a \n at all.

FWIW I think we can do without the comment...

This appears to be some shell pseudo-syntax, and my shell hard-errors on
this.
But as we don't "shift" after the "$1" I don't see how what you
*probably* meant could work, i.e. we always have arguments, so surely
we'd always use "$@"?

You're just testing how these options interact, so let's have the
"foobar" part provided by the test function itself.
