[PATCH v3 11/22] worktree: simplify new branch (-b/-B) option checking

From
Eric Sunshine <sunshine@sunshineco.com>
Date
Jul 17, 2015, 23:00 UTC
Message-ID

Make 'new_branch' be the name of the new branch for both forced and non-forced cases; and add boolean 'force_new_branch' to indicate forced branch creation. This will simplify logic later on when git-worktree handles branch creation locally rather than delegating it to git-checkout as part of the worktree population phase.
