#36 Co-authors with same last name appear only once

[Stephan Vollmer]

On the author pages, the co-author list has a bug:

When two co-author have the same last name, only one
author appears in the co-author list, but with
references to both publications.

Example:
http://dblp.dyndns.org:8080/dblptest/jsp/author.jsp?author=Ludovic+Denoyer

The names "Sylvie Brunessaux" and "Stephan Brunessaux"
appear as "Sylvie Brunessaux".
