[emacs-w3m:12018] buffer:// under home directory

With recent debian i386 emacs 24.3 and the current cvs w3m, if you have
a file foo.html in your home directory then

    M-x find-file ~/foo.html        # into buffer foo.html
    M-x w3m-browse-url buffer://foo.html

gets

    Cannot retrieve URL: file://~/foo.html

default-directory starts with a "~" when under the home directory which
it seems is no good for file://.

An expand-file-name per below does the trick.  But then I wondered if
perhaps

    (buffer-file-name (get-buffer ...))

would help if the buffer name isn't the filename, eg. foo.html<2>.

Is buffer:// a documented feature?  I suppose it could do something like
w3m-region to take the buffer content instead of the file content in
case you haven't saved, or for a non-file buffer.  But perhaps it's not
that sophisticated yet.

I struck this when tinkering with a way to have w3m preview html while
editing, and perhaps rendering buffers like a tar file member if
browsing source archive etc.  I made a copy to a temp file, but that
loses the current directory for relative links.  Perhaps there's
something better already which I don't know.

[emacs-w3m:12005] cookies dropped

Here is a problem that happens in emacs-w3m but works fine in w3m.

The problem is that cookies are all dropped in this case...

[emacs-w3m:11997] strange behavior of w3m-session-rename

Hi,

Please kindly CC me, so that I get the reply.

Suppose I open a session-select buffer by w3m-session-select, and find
"Crash recovery sessions[n]" contains couple of pages for learning w3m.
I want rename it to "w3m tutorials". So, I press 'r' and input the name
and expect the session in question be renamed, but emacs-w3m refuse to
do this for me. It keeps asking me "Again New session title: "

Ah. I took a look at the function w3m-session-delete. It seems the
following patch will help it to do what I want.

    --- w3m-session.el.~1.34.~	2012-02-13 08:46:40.000000000 +0800
    +++ w3m-session.el	2013-04-12 10:49:22.193344150 +0800
     <at>  <at>  -731,7 +731,9  <at>  <at> 
     	     ((assoc title sessions)
     	      (when (y-or-n-p (format "\"%s\" is exist. Overwrite? " title))
     		(setq overwrite t)
    -		(throw 'loop t))))
    +		(throw 'loop t)))
    +         (t
    +          (throw 'loop t)))
     	    (setq prompt "Again New session title: ")))
     	(when overwrite
     	  (setq sessions (delete (assoc title sessions) sessions)))

I wonder whether this is what the what the author mean to do. Or, I just
have a another way of rename the sessions in "*w3m-session select*"
buffer.

[emacs-w3m:11990] error on <select> with empty name

With recent debian i386 emacs 24.2.1 and cvs w3m, the file foo.html
below viewed with M-x w3m-find-file gets an error

    Wrong type argument: stringp, ("1" ("1" . "AAA") ("2" . "BBB"))

backtrace.txt below from the debugger.

Dunno if foo.html is legal html or not, but even if not I hoped it
wouldn't error out but display some sort of approximation.

I wonder if it's related to the <select name=""> being empty "".
Putting something non-empty in there works.
