biblatex 超链接后不需要多余的空格

我正在用biblatex它作为参考，发现了chem-angew我非常欣赏的风格。

我找到了如何在期刊标题下添加超文本链接的方法，而且效果很好。但有一个小问题：我不知道如何删除超文本链接造成的多余空格（如果我删除超链接，多余空格就会消失）。请注意，如果链接后面跟着逗号，则没有问题……但在样式中chem-angew，期刊标题和年份之间没有逗号。我希望超文本链接位于期刊标题下方。

有人知道该怎么办吗？我必须完全定义自己的biblatex风格吗？

这是我的代码：

\documentclass{book}

\usepackage[backend=biber,
        style=chem-angew,
        firstinits=true,
        maxbibnames=99]{biblatex}
\renewbibmacro{in:}{}
\addbibresource{library2.bib}

\usepackage{hyperref}
\hypersetup{urlcolor=black, colorlinks=true}

I really wonder why there is an extra space in the bibliography \cite{Bocquet2010}!
I wish I could erase it \cite{Nicholls2012}. 
However, it depends on what type of document you cite \cite{Palacci2010}.
\label{Bibliography}
\printbibliography

以下是.bib：

doi = {10.1039/B909366B},

最后，这是我通过这段代码得到的结果： 在此处输入图片描述

非常感谢那些可能需要一些时间来回答的人。

答案1

Joseph Wright 刚刚修复问题适当地。

这是因为removecomma中使用了特殊字段格式\renewbibmacro*{journal}，并定义为\DeclareFieldFormat{removecomma}{\mkbibnocomma{#1}}。

具体来说，空格是由\scantokens命令在

\newcommand*\mkbibnocomma[1]{%
  \begingroup
    \catcode`\, = 9\relax
    \scantokens{#1}%
  \endgroup
}

另请参阅@egreg 的回答有人可以进一步阐明扩展、catcodes 和 scantokens……吗？

通常，该空间会被标点符号命令发出的 s 占用\unspace，但一旦空间进入 hyperref 命令，它似乎就太晚了。

暂时重新定义为

\renewcommand*\mkbibnocomma[1]{%
  \begingroup
    \catcode`\, = 9\relax
    \scantokens{#1\empty}%
  \endgroup
}

我们得到了正确的输出。
