或多或少，我故意创建了这个场景：
# We use git-flow.
$ git flow feature start <feature>
# update a file
$ git commit <file> -m '<message>'
$ git rebase -i develop
$ git push -u origin <feature-branch>
# Try arcanist now
$ arc diff
# diff was accepted
$ git flow feature finish <feature>
# feature branch removed, now in develop, let's push
$ git push
所以现在我处于分支消失的状态，由于本地分支不可用，我无法登陆。 注意：git（和 gitolite）工作得很好
$ arc land
Exception
Branch "<feature-branch>" does not exist in the local working copy.
/rant.. 我在 Phabricator 的 Maniphest 中没有看到我的功能分支。为什么不？
我可以拉回那个分支：
$ git fetch -a
$ git checkout <feature-branch>
但我仍然无法登陆：
$ arc land
Landing current branch '<feature-branch>'.
TARGET Landing onto "<feature-branch>", selected by following tracking branches upstream to the closest remote.
REMOTE Using remote "origin", selected by following tracking branches upstream to the closest remote.
FETCH Fetching origin/<feature-branch>...
Usage Exception: There are no commits on "<feature-branch>" which are not already present on the target.
据我所知，我没有办法关闭该差异。我该如何恢复？
