Add a variable to cmd_branch() that will tell us whether or not cmd_branch() will default to creating a branch (instead of performing another action). Besides making the function more explicit, this allows us to validate options that can only be used when creating a branch. Such an option does not exist yet, but one will be introduced in a subsequent commit.
