Bug in body refs to other messages

I've been running my archives through weblint, and find an odd error 
popping up.  It's when a message has a line of the form "in message 
<12345(_at_)somewhere(_dot_)com>, so-and-so wrote": MHonArc cleverly tries to 
create a link to that message, but it puts the HREF in twice, as in 
the fragment below.  It seems to work, but its very bad HTML :(

Is there any reconfiguation I can do my resource files to cure this?

HTML fragment:

In article &lt;<A HREF="msg00007.htm"><A 
HREF="msg00007.htm">199801130753_MC2-2F23-E6F5(_at_)compuserve(_dot_)com</A></A>
&gt;, Jane Doe
