如何更改首字母缩略词的格式？

Question

我使用这个acronym包。请帮我更改缩写词和全名之间的空格，并在它们之间添加一个破折号，如下所示：

PG       - some text

HRoT     - some text some text some text some text some       
           text some   text some text some text some text some text

我还想让缩写以罗马文本样式显示（默认情况下为粗体）

  \documentclass[12pt]{report} 
  \usepackage{fontspec}
  \usepackage{xunicode}
  \usepackage[no-sscript]{xltxtra}
  \usepackage[babel=false]{csquotes}
  \usepackage{polyglossia}
  \setdefaultlanguage{french}
  \setotherlanguages{german,english,greek,polish,russian}
  \setmainfont[Mapping=tex-text]{Linux Libertine}
  \usepackage{acronym}

  \makeatletter
  \def\uplabel#1{{\normalfont{\textsf{#1}}\hfill}-}
  \renewenvironment{AC@deflist}[1]%
    {\ifAC@nolist%
     \else%
        \raggedright\begin{list}{}%
            {\settowidth{\labelwidth}{\normalfont{\textsf{#1}}\hspace*{3em}}% change 2em to the desired value
            \setlength{\leftmargin}{\labelwidth}%
            \addtolength{\leftmargin}{\labelsep}%
            \renewcommand{\makelabel}{\uplabel}}%
      \fi}%
    {\ifAC@nolist%
     \else%
        \end{list}%
     \fi}%
  \makeatother

  \begin{document}
  \begin{acronym}
  \acro{Esj}{some text some text some text some text some text some text some text some text some textsome text some text some text}

  \acro{At}{some text some text some text some text some text some text some text some text some text some text some textsome textsome text some text some text}
  \end{acronym}
  \end{document}

该文件acronym.sty使用\bflabel粗体和小写字母排版标签；我定义了一个新的宏\uplabel，它使用\normalfont而不是粗体系列，并包含一个连字符来分隔首字母缩略词及其定义；此命令将在AC@deflist格式化首字母缩略词列表的环境中使用，并且必须重新定义以增加首字母缩略词与其定义之间的分离。环境acronym也必须重新定义。

在前言中添加以下几行（在acronym包加载之后）并根据需要更改使用的值：

\documentclass[12pt]{report} 
  \usepackage{fontspec}
  \usepackage{xunicode}
  \usepackage[no-sscript]{xltxtra}
  \usepackage[babel=false]{csquotes}
  \usepackage{polyglossia}
  \setdefaultlanguage{french}
  \setotherlanguages{german,english,greek,polish,russian}
  \setmainfont[Mapping=tex-text]{Linux Libertine}
  \usepackage{acronym}
\usepackage{enumitem}

\renewcommand\acsfont{\normalfont}

\makeatletter
\def\uplabel#1{{\normalfont{\textsf{#1}}\hfill}-}
\renewenvironment{acronym}[1][1]{%
   \providecommand*{\acro}{\AC@acro}%
   \providecommand*{\acroplural}{\AC@acroplural}%
   \long\def\acroextra##1{##1}%
   \def\@tempa{1}\def\@tempb{#1}%
   \ifx\@tempa\@tempb%
      \global\expandafter\let\csname ac@des@mark\endcsname\AC@used%
      \ifAC@nolist%
      \else%
         \begin{list}{}%
                {\settowidth{\labelwidth}{\normalfont{\textsf{#1}}\hspace*{3em}}% change according to your needs
                \setlength{\leftmargin}{\labelwidth}%
                \addtolength{\leftmargin}{\labelsep}%
                \renewcommand{\makelabel}{\uplabel}}
      \fi%
   \else%
      \begin{AC@deflist}{#1}%
   \fi%
  }%
  {%
   \ifx\AC@populated\AC@used\else%
      \ifAC@nolist%
      \else%
          \item[]\relax%
      \fi%
   \fi%
   \expandafter\ifx\csname ac@des@mark\endcsname\AC@used%
      \ifAC@nolist%
      \else%
        \end{list}%
      \fi%
   \else%
      \end{AC@deflist}%
   \fi}%
\renewenvironment{AC@deflist}[1]%
        {\ifAC@nolist%
         \else%
            \raggedright\begin{list}{}%
                {\settowidth{\labelwidth}{\normalfont{\textsf{#1}}\hspace*{3em}}% change according to your needs
                \setlength{\leftmargin}{\labelwidth}%
                \addtolength{\leftmargin}{\labelsep}%
                \renewcommand{\makelabel}{\uplabel}}%
          \fi}%
        {\ifAC@nolist%
         \else%
            \end{list}%
         \fi}%
 \makeatother

  \begin{document}
  \begin{acronym}
  \acro{Esj}{some text some text some text some text some text some text some text some text some textsome text some text some text}

  \acro{At}{some text some text some text some text some text some text some text some text some text some text some textsome textsome text some text some text}
  \end{acronym}
