So far I got no idea for making C-c C-c work as well as the button
press.  While things to be sent are obviously different between
them, both have been working for many web sites.  Though emacs-w3m
will work even if the C-c C-c feature is lost, I don't want to do
it.  Maybe we need people having excellent knowledge about the http
communication (and ELisp, of course).
