Man Page Links with "_" (underscore) in Name Broken on OpenBSD Man Website

In case no one has noticed (I can't find any reports of this in the www 
archive):

At least some OpenBSD Man Website Man page links in the SEE ALSO section 
are broken.  These appear to be all links to sections with an underscore 
("_") in the name.

To see issue:

  1 - http://www.openbsd.org/cgi-bin/man.cgi
  2 - search for 'troff'
  3 - scroll to SEE ALSO section at bottom
  4 - note the lack of full hyperlinks on any section with '_' in the
      name.
  5 - click on 'groff_char(7)'
  --> Sorry, no data found for `char(7)'.

If you do a man page search for "groff_char" (ensuring that your search 
is for section 7 or for all sections), you will get the page needed.
