防止 biblatex 书目中的 URL 出现换行符

Question

与大多数人不同，我试图防止破坏我的参考书目中的 URL。在下面的例子中，第一个项目中的 URL 应该保持原样，因为它没有跨行。第二个项目中的 URL 太长，无法放在它开始的那一行，所以它跨了两行。在这种情况下，URL 应该单独放在最后一行。简而言之，我只是想防止 URL 中出现换行。参考书目条目应该像平常一样对齐。

\RequirePackage{filecontents}
\begin{filecontents*}{\jobname.bib}
@BOOK{indreboe1951,
  AUTHOR    = {Gustav Indreb\o},
  TITLE     = {Norsk m\aa lsoga},
  YEAR      = {1951},
  LOCATION  = {Bergen},
  PUBLISHER = {John Grieg},
  URL       = {http://urn.nb.no/URN:NBN:no-nb_digibok_2010110808058},
}
\end{filecontents*}


\documentclass{article}
\usepackage[%
  paper = a4paper, vmargin = 1in,
  showframe
]{geometry}
%\usepackage{ragged2e}
\usepackage{microtype}

\usepackage[%
  style = authoryear-comp,
  backend=biber,
]{biblatex}
