If --force is not given but -B is, we should not proceed if the given branch is already checked out elsewhere. add_worktree() has this test, but it kicks in too late when "git branch --force" is already executed. As a result, even though we correctly refuse to create a new worktree, we have already updated the branch and mess up the other checkout. Repeat the die_if_checked_out() test again for this specific case before "git branch" runs. Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
