目录：页码与顶部对齐，而不是底部对齐

Question

简单来说，我该如何将页码对齐到很长的目录条目的顶部？

以下是 MWE：

\documentclass{book}
\usepackage{tocloft}% http://ctan.org/pkg/tocloft
\usepackage{etoolbox}% http://ctan.org/pkg/etoolbox

\newcommand{\listdefinitionname}{My list of definitions}
\newlistof{definition}{def}{\listdefinitionname}
\newcommand{\definition}[1]{%
  \refstepcounter{definition}%
  \par\noindent\textbf{The Definition~\thedefinition. #1}%
  \addcontentsline{def}{definition}
    {\protect\numberline{\thechapter.\thedefinition}#1}\par%
}
\makeatletter
\preto\chapter{\addtocontents{def}{\protect\addvspace{10\p@}}}%
\makeatother

\begin{document}

\listofdefinition
\chapter{A chapter}
\definition{Some really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really long definition}
\definition{Some definition}
\definition{Some definition}


\end{document}

根据 Manual Kuehner 博士的评论，你可以调整egreg 的解决方案从目录对齐问题，多\pbox行\includepdfaddtotoc：

\documentclass{book}
\usepackage{tocloft}
\usepackage{xpatch}

\usepackage{varwidth}
\makeatletter
\DeclareRobustCommand{\vwdef}[1]{%
  \begin{varwidth}[t]{\dimexpr\textwidth-\@pnumwidth-\cftdefinitionnumwidth}\strut#1\unskip\nobreak\strut\par
  \end{varwidth}%
}
\makeatother

\newcommand{\listdefinitionname}{My list of definitions}
\newlistof{definition}{def}{\listdefinitionname}
\newcommand{\definition}[1]{%
  \refstepcounter{definition}%
  \par\noindent\textbf{The Definition~\thedefinition. #1}%
  \addcontentsline{def}{definition}
    {\protect\numberline{\thechapter.\thedefinition}\vwdef{#1}}\par%
}
\setlength{\cftdefinitionnumwidth}{2em}

\xpretocmd\chapter{\addtocontents{def}{\protect\addvspace{10pt}}}{}{}%

\begin{document}

\listofdefinition
\chapter{A chapter}
\definition{Some really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really long definition}
\definition{Some definition}
\definition{Some definition}

\end{document}
