我们如何抑制这个，它只是生成补丁文件的git版本？

Answer 1

使用git format-patch --no-signature 标志：

       --[no-]signature=<signature>
           Add a signature to each message produced. Per RFC 3676 the signature is separated from the
           body by a line with '-- ' on it. If the signature option is omitted the signature defaults
           to the Git version number.
