Line breaks in urlindex

Question

In this discussion here, Heiko gave me a great answer, but now i have a line breaks problem. If I write \href{http://www.legifrance.gouv.fr/affichTexte.do?cidTexte=LEGITEXT000006055121&dateTexte=20110206}{blabla} I get an overfullhbox, and It's not very beautifull. Is There a way to fix it? Thanks. The mwe is in the link above.

If I use a text width of 100cm I have no overfull. ;-). Seriously, this depends on the text width and on where the object is placed. Can you make a minimal working example (MWE) showing the issue? — egreg, Apr 28 '14 at 10:56

My suggestion is to add \raggedright to the definition of the UrlListEnv environment:

% Environment UrlListEnv surrounds the list of URLs, if
% URLs are available.
\newenvironment{UrlListEnv}{%
  \raggedright
  \begin{description}%
}{%
  \end{description}%
}

With just this change the output is

enter image description here

Trying to justify such long URLs is hopeless.
