Subject: [PATCH 4/6] worktree move: accept destination as directory

From: Nguyễn Thái Ngọc Duy <[email-masked]>
Date: Thu, 20 Apr 2017 17:10:22 +0700

Similar to "mv a b/", which is actually "mv a b/a", we extract basename
of source worktree and create a directory of the same name at
destination if dst path is a directory.
