emacs-w3m-CVS doesn't decode form submit URLs properly 

Dear Bug Team!

i've got a wiki running here, and when saving an edited page, the URL
submitted looks like

  http://127.0.0.1:8882/cgi/awki.cgi?save=true&page=ClemensFischer

this URI should have been:

  http://127.0.0.1:8882/cgi/awki.cgi?save=true&page=ClemensFischer

(note `&' instead of `&')

thus the not-so-smart CGI thinks the URI is finished or useless after
`... ?save=true...' and doesn't see the page name to be saved.  this
will always overwrite my FrontPage and renders emacs-w3m useless for
this particular task.  that is unfortunate, because i'm kind of
addicted to emacs-w3m and use it all the time.

i checked this behaviour with elinks and w3m from the command line,
and these browsers do not exhibit this bug.  the bug can be repeated
anytime.

the HTML of the page in question just before submitting the edit is:

<html>
<head>
<title>FrontPage</title>
</head>
<body>
<h1><img src="/awki.png" width="48" height="39" align="left">
<a href="/cgi/awki.cgi/FullSearch?string=FrontPage">FrontPage</a></h1><hr>
<form action="/cgi/awki.cgi?save=true&amp;page=FrontPage" method="POST">
<textarea name="text" rows=25 cols=80>

<form action="/cgi/awki.cgi/FullSearch" method="GET" align="right">
<input type="text" name="string">
<input type="submit" value="search">
</form>
</body>
</html>

(sequences of `...' are ellipses by me to shorten this report).
