Subject: [PATCH v3 05/25] upload-pack: remove unused variable "backup"

From: Nguyễn Thái Ngọc Duy <[email-masked]>
Date: Tue, 23 Feb 2016 20:44:43 +0700

After the last patch, "result" and "backup" are the same. "result" used
to move, but the movement is now contained in send_shallow(). Delete
this redundant variable.
