有时，旧文本的编辑会认为某一节的行号断错了。由于他们不能简单地放弃使用已使用数百年的旧编号，因此他们会将旧编号与新换行符结合起来，这样这些行号就被称为 10、11/12 和 12/13。
简单的例子：假设遗产执行人发现一首著名诗歌的手写草稿，其停顿与排字员的不同。

答案1
reledmac 2.26.0 版本，刚刚在 CTAN 上发布，提供可以给行号添加“注释”的系统。Suche 注释：
- 可以是任意的文本内容，例如较旧的行号
- 每行自动重置
- 添加在边距中
- 已添加于脚注中。

\title{Stanza with double line numbering}
\maketitle
\begin{abstract}
This file provides an example of typesetting verse with reledmac using a double line numbering system.
The new edition adds a starting line of verse not present in the previous one, so we need to make an addition within the margin and textsuperscript the numbering from the older edition. In the centre, we split what was in the first edition one line of verse into two.
To mark the old numbering, we use \verb+\linenumannotation+. For maximum clarity, all line numbers are shown thanks to the settings of \verb+\firstlinenum+ and \verb+\linenumincrement+ in the preamble.
