Line breaks inside {code} ... {code} tags are incorrectly rendered in PDF

Create a document with several lines of text inside {code} ...\ {code} tags and
then export this document as PDF using the appropriate function of XWiki

Result: In the PDF document the line breaks are not the same as in the original XWiki document.

As an example, see <http://www.xwiki.org/xwiki/bin/view/Main/PostgresHibernate>
