w3m-clear-display-while-reading vs C-c C-k stop

[Kevin Ryde <user42_kevin@xxxxxxxxxxxx>]

When w3m-clear-display-while-reading is t (the default), if a web server
is unresponsive then going C-c C-k to stop the sub-process (as invited
by the usual echo area message) leaves the display cleared and showing
"Reading http://..."

I wonder if C-c C-k could redraw the page it came from.  The status bar
seems to show the title, but no content in the buffer.  If a cancel of
the first fetch of a session then maybe blank or something.

A bit of netcat locally can cook up an unresponsive server to see the
effect.  I've usually struck it on domains gone or down.

    netcat -l -p 12345

then in emacs

    M-x w3m
    g http://localhost:12345/
    C-c C-k
    =>
    still shows "Reading ..."
