Subject: [PATCH] Adjust diff-helper to diff-tree -v -z changes.

The latest change to diff-tree -z output adds an extra line
termination after non diff-raw material (the header and the
commit message).  To compensate for this change, stop adding the
output termination of our own.  "diff-tree -v -z" piped to
"diff-helper -z" would give different result from "diff-tree -v"
piped to "diff-helper" without this change.
