我的理解\markboth是，它设置了用于标题的标签，但它不会立即在文档中产生任何输出。但是，我发现，如果您\markboth在 reledmac 节中调用，它会在文档中产生可见的输出。
下面是我所指的输出类型的示例：
如您所见，\markboth从 reledmac 节内部调用会在文档中产生一行空白的输出。
演示此内容的 MWE 如下：
\documentclass[10pt,openany]{book}
\usepackage{reledmac}
\usepackage{fancyhdr}
\usepackage[paperheight=9in,paperwidth=6in,asymmetric]{geometry}
\pagestyle{fancy}
\fancyhead[LE,RO]{\rightmark--\leftmark}
\newcommand{\showverse}[2]{%
\raisebox{0.5ex}{#2}\nobreak\hspace*{0.2em}%
}
\setstanzaindents{2,1}
\setcounter{stanzaindentsrepetition}{1}
\setlength{\stanzaindentbase}{30pt}
\firstlinenum{100}
\begin{document}
\markboth{1:1}{1:1}\showverse{1}{1}Now is the time for all good men to come to the aid of their country.
\markboth{1:1}{1:1}\showverse{1}{2}Now is the time for all good men to come to the aid of their country.
\markboth{1:1}{1:1}\showverse{1}{3}Now is the time for all good men to come to the aid of their country.
\beginnumbering
\stanza
This is a line of verse&
\markboth{1:4}{1:4}\showverse{1}{4}And another line of verse& % <=== \markboth produces visible output
And the last line of verse\&
\endnumbering
\end{document}
删除该\markboth命令会产生以下输出：
有谁知道我可以在 reledmac 节中调用而不产生此空行输出的方法吗\markboth？另外，有谁看到我做错了什么导致这种情况？

\doinsidethislinehook您必须按照手册第 5.7 节的说明使用。
\documentclass[10pt,openany]{book}
\usepackage{reledmac}

\newcommand{\showverse}[2]{%
\raisebox{0.5ex}{#2}\nobreak\hspace*{0.2em}%
}
\setstanzaindents{2,1}
\setcounter{stanzaindentsrepetition}{1}
\setlength{\stanzaindentbase}{30pt}
\firstlinenum{100}
\begin{document}
\markboth{1:1}{1:1}\showverse{1}{1}Now is the time for all good men to come to the aid of their country.
\markboth{1:1}{1:1}\showverse{1}{2}Now is the time for all good men to come to the aid of their country.
\markboth{1:1}{1:1}\showverse{1}{3}Now is the time for all good men to come to the aid of their country.
\beginnumbering
