我喜欢 vim，而且我真的很喜欢在编写文本时对它们进行硬包装。Tim Pope 的 markdown 插件很棒，它的构建使得当我尝试硬包装一个项目列表时，它可以正确地完成工作。好的，这就是我正确完成工作的意思：
- here I write a long long long line that is longer than the 80 caracters of a line and therefore should be wrapped.
- This is a short line
- here I write another long long long line that is longer than the 80 caracters of a line and therefore should be wrapped.
应该变成（应用gqap之后）：
- here I write a long long long line that is longer than the 80 caracters
of a line and therefore should be wrapped.
- This is a short line
- here I write another long long long line that is longer than the 80 caracters
of a line and therefore should be wrapped.
现在，对于具有 tex 文件类型的文本，同一命令的行为并不那么聪明：
\begin{itemize}
\item here I write a long long long line that is longer than the 80 caracters I fixed and therefore should be wrapped.
\item This is a short line
\item here I write another long long long line that is longer than the 80 caracters I fixed and therefore should be wrapped.
\end{itemize}
变为（仍然在 gqap 之后）：
\begin{itemize} \item here I write a long long long line that is longer than
the 80 caracters I fixed and therefore should be wrapped. \item This
is a short line \item here I write another long long long line that is
longer than the 80 caracters I fixed and therefore should be wrapped.
\end{itemize}
如何使 LateX 中项目列表的包装表现得像降价列表？
在我看来，我应该重新定义语法文件，但我不知道如何（markdown 的工作方式是使用为 HTML 定义的元素）。
