Backport #28719 by wxiaoguang In #26851, it assumed that `Commit` always exists when `PageIsDiff==true`. But for a 404 page, the `Commit` doesn't exist, so the following code would cause panic because nil value can't be passed as string parameter to `IsMultilineCommitMessage(string)` (or the StringUtils.Cut in later PRs) Co-authored-by: wxiaoguang <wxiaoguang@gmail.com>
