viewing an email that is only content type HTML

[Eric S Fraga <ucecesf@ucl.ac.uk>]

Hello,

I have no problem reading emails which contain HTML entities.
However, I often (increasingly and annoyingly so) get emails which are
solely HTML.  Even the ones that are well specified, including for
instance the "Content-Type: text/html; charset=utf-8" type of header
entry, are displayed in raw mode.  That is, I see the actual HTML
code.

How can I configure Wl either to show me the interpreted contents
(e.g. as I would get if I piped the message body through w3m or links
or equivalent) or leave the contents hidden but with a means to spawn
an external or emacs internal HTML viewer if desired?  Of, even if the
raw contents are shown, how can I spawn an external viewer or use an
internal viewingmode on the whole message?

Thanks for any suggestions or pointers!

PS - I am using wl-beta (2.15.6+0.20090322-1) on Debian testing/unstable.
