I'm afraid I was a bit rushed before. Here's a version worked up as a  
macro which is non-redundant:

\documentclass{minimal}

\setlength{\textwidth}{2.375in}
\setlength{\parindent}{0pt}

\newcommand{\magicmacro}[1]{\hfill\allowbreak\strut\hfill{#1\parfillskip 
=0pt\par\unskip\parfillskip=0pt plus 1fil}}

\begin{document}
[1]  Author 1, Title bla bla blabla blabla
      sept. 2004.        \magicmacro{urlurlurlurlurlurl}


and here where it doesn't

[1]  Author 1, Title bla bla blabla blabla
      some more bla, sept. 2004.
\magicmacro{urlurlurlurlurlurl}


This is an extra paragraph.
\end{document}
