Save the SOURCE of the current page to a file

[jidanni@xxxxxxxxxxx]

We see
d	Download the file or the page under point.
Please say
d	Download the URL under point.
to match the error message "No URL at point".

We also find
M-i	Save the image under point to a file.

OK, but we are still missing a command to
	Save the SOURCE of the current page to a file.

Currently we must do "\ C-x C-w filename", or
"B d filename".

Also mention what to do on (info "(emacs-w3m)Downloading").
