some wiki links on SF web site are broken

For example, http://docbook.sourceforge.net/ links to
http://wiki.docbook.org/topic/DocBookXslStylesheets, but that gives a
404 response, and the correct link is
http://wiki.docbook.org/DocBookXslStylesheets.  Apparently, there was a
change in the wiki's URL scheme.  I have noticed links from other sites
that are broken as well, so this might have been a recent change.
