BibTeX, biblatex and biber ⇒ hyperref | Line Break too early with 'pagebackref' Option

[karl-ranseier]

Hi,
I think hyperref produces an unnecessary line break when using the "pagebackref" option. My example is:

Code: Select all

\documentclass[pdftex]{scrbook}
\usepackage[pagebackref]{hyperref} 

\begin{document}
\bibliographystyle{plain}
\cite{Minimal}\clearpage
\cite{Minimal}\clearpage
\bibliography{bibi}
\end{document}

using the bibi.bib content:

Code: Select all

@ARTICLE{Minimal,
  author = {A. Aaaaa and A. Aaaaa and A. Aaaaa and A. Aaaaa and A. Aaaaa and A. Aaaaa},
  title = {BBBBBB BBBBBBBB BBBBBBBBB BBBBBBb},
  journal = {CCCCCCCCC CCCCCCCCC},
  year = {2042},
  volume = {42},
  pages = {42}
}

It produces this:

linebreak.jpg (31.51 KiB) Viewed 1858 times

Using only one C less in the journal produces:

nolinebreak.jpg (30.27 KiB) Viewed 1858 times

One may see, that there is enough space for more than one C, so in my opinion the line break is too early. Basically this behaviour is acceptable. But using my own .bst file, where I replaced the the fin.entry function to fill out the gap between the page back references and the citation:

Code: Select all

FUNCTION {fin.entry}
{ write$
  " {\hfill} " write$
  newline$
}

It produces, using some modifications in the length of the bib-entry, this ugly behaviour:

hfill.jpg (24.83 KiB) Viewed 1858 times

The expected behaviour (produced with different content in the bibi.bib) looks like this:

hfillok.jpg (30.78 KiB) Viewed 1858 times

Does anyone have some hints how to fix this problem? Am I right, that the problem is produced as shown in my source code example? Or shall I post my *.bst file? Am I in the wrong forum?


kind regards

Moved the problem to another discussion group:
http://groups.google.com/group/comp.tex ... b315821273#

These settings in the preamble work fine:

Code: Select all

\adjdemerits=6666 % Default 10000
\linepenalty=77 %Default=?
