今天我发现了 numeric-comp 样式的一个奇怪行为。由于我使用的是较大的引用列表，因此列表中的引用出现了两次，结果只有第一个引用被引用。
\documentclass{article}
\usepackage[style=numeric-comp,backend=biber]{biblatex}
\addbibresource{biblatex-examples.bib}
\listfiles
\begin{document}
\section{foo}
This works:
\cite{companion,knuth:ct,knuth:ct:a,knuth:ct:b,knuth:ct:c}
This is how to damage it:
\cite{knuth:ct:c,companion,knuth:ct,knuth:ct:a,knuth:ct:b,knuth:ct:c}
\printbibliography
\end{document}
如果我使用第二个 cite 命令，输出不应该也是 [1-5] 吗？
