missing part of Subject from & on

http://www.amnesty-caribbean.org/Petitionstext.html contains a form that
results in

POST http://amnesty-caribbean.org/cgi-local/textout.pl/petition/format.txt&/petition/result.txt

www4mail responds correctly, except that the subject says

Subject: Requested (URL - http://amnesty-caribbean.org/cgi-local/textout.pl/petition/format.txt)

The part from the & on has been removed.
In the Details for Current Page the & has been substituted by ?.
Saluton!	Dietmar P. Schindler
