Re: emacs-w3m can't send post data to the form which has a form with 'enctype=multipart/form'.

Hi,

We're sorry for a late response.  Persons who are familiar with
forms seem to be busy now.  Though I'm not well informed to
forms, I seem to have solved the problem.  Please try the CVS
version.

Emacswiki specifies the "get" method for "multipart/form-data",
however RFC2070 recommends to use the "post" method as follows:

5.2. Form submission
[...]
   The best solution is to use the "multipart/form-data" media type
   described in [RFC1867] with the POST method of form submission.

And the cause of the problem is that emacs-w3m cannot send such
data using the "get" method.  I've modified w3m-form.el so as to
use the "post" method in such a case.
