@copilot 解释为什么会有这个diff 这两行内容是一样的 #1409 (comment)

The two lines have identical visible text content. The diff exists solely because of a trailing newline change at the end of the file. The old version was missing a newline at EOF (git marks this with \ No newline at end of file), and this commit added one. That's why git shows a diff even though the line text looks the same.
