Patch to support emacs-w3m


Thank you for sending the patch.  I tried it with VM 7.17 and
confirmed it works well with no problems.  I wrote this message
using VM (I don't have a mind to change my temple from Gnus to
VM, though ;-).

There are many maintainers in the emacs-w3m community. :)

Well, I don't encounter that problem so far.  Could you forward
me a sample mail containing the <title_alt title="FOO"> form?
I apologize in advance. I cannot work at all till next week.

By the way, I tried a little improvement.  The patch attached in
this mail makes it possible to use some emacs-w3m command keys
in the VM presentation buffer.  It will need to be further
improved in order to enable it to treat the cid: urls (which is
used to embed real HTML contents in the multipart/related style
MIME message) properly as Gnus does.  However, please don't
request a new code to me, since I don't know how does VM parse
MIME parts. ;-)

Have a nice weekend,
