我有以下 markdown 文件演示了该问题（至少在我的环境中）：

# Example
An example of the double-hyphen wrapping issue.
## Process
See below.
### List Process
The `--all` flag can be used to list all processes that have been started. The `--pid` and `--uniqueid`
arguments can be used to display information about a specific pid or unique id, respectively. If
called with the `--verbose` flag, the command will display the complete output of the process, as well
as the Exit Code, Run Time, and other process information, if available.
上面的代码可能可以稍微缩短一点，但确实说明了这个问题。 被--pid包裹在第一个和第二个连字符之间。我不希望它在第一个连字符之前被包裹。
我使用 pandoc 生成 LaTeX 文件，然后使用 pdflatex 处理该文件生成 PDF 文件。
LaTeX 文件太大，无法在此处放置，但文件主体包含上述内容的部分如下（我将标题页、目录、故意留空的页和修订表保留在下面）：
\begin{document}

\subsubsection{List Process}\label{list-process}
The \texttt{-\/-all} flag can be used to list all processes that have
been started. The \texttt{-\/-pid} and
\texttt{-\/-uniqueid} arguments can be used to display information
about a specific pid or unique id, respectively. If
called with the \texttt{-\/-verbose} flag, the command will display the
complete output of the process, as well as the Exit Code, Run Time, and
other process information, if available.
\end{document}
我的 template.latex 文件中有以下定义\texttt，这是防止长命令自动换行所必需的：
\let\oldTexttt\texttt
\renewcommand{\texttt}[1]{%
\hyphenpenalty=10000
\exhyphenpenalty=10000
\setlength{\emergencystretch}{6em}
\setlhcolor{codegray}%
{\ttfamily\hl{#1}}%
\setlength{\emergencystretch}{3em}
\exhyphenpenalty=50
\hyphenpenalty=50
}
我希望能够修改上述\texttt定义来获得我需要的内容，而不必编辑源文件或来自 pandoc 的 LaTeX 文件。

我希望这有帮助。

由于您已经对参数进行了替换，因此您可以将其扩展为替换-\/-为\mbox{-\/-}：
\documentclass[12pt,]{article}
\usepackage{lmodern}
\usepackage{mathptmx} % makes Time New Roman the default font
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
% use upquote if available, for straight quotes in vebatim environments
\IfFileExists{upquote.sty}{\usepackage{upquote}}{}
% use microtype if available
\IfFileExists{microtype.sty}{%
\usepackage[]{microtype}
\UseMicrotypeSet[protrusion,expansion]{basicmath} % disable protrusion for tt fonts
}{}
\usepackage[margin=1in]{geometry}
\usepackage{listings}
\setlength{\emergencystretch}{3em} % prevent overfull lines
\usepackage{parskip}
\usepackage{xcolor}
\usepackage{soul}
\definecolor{codegray}{HTML}{F0F0F0}
\definecolor{framegray}{HTML}{C0C0C0}
\sethlcolor{graycode}
% unbreak escaped space character in inline codeblocks
\usepackage{xparse}
\usepackage{ragged2e}
\let\hlORIG\hl
\ExplSyntaxOn
\tl_new:N \l_jdhao_hlx_tl
\RenewDocumentCommand\hl{m}{%
\tl_set:Nn\l_jdhao_hlx_tl{#1}%
\tl_replace_all:Nnn\l_jdhao_hlx_tl{\ }{~}%
\tl_replace_all:Nnn\l_jdhao_hlx_tl{-\/-}{\mbox{-\/-}}% added
\exp_args:NV\hlORIG\l_jdhao_hlx_tl}%
\ExplSyntaxOff
% override the inline coding style to show gray highlight box
\let\oldTexttt\texttt
\renewcommand{\texttt}[1]{%
\sethlcolor{codegray}%
{\ttfamily\hl{#1}}%
}
\begin{document}
The \texttt{-\/-all} flag can be used to list all processes that have

更改文本中的所有惩罚等是没有意义的：设置是段落值。
