While I'm sure Laura's command above works well as an HTML viewer for an
MUA such as might be specified in a mutt mailcap file, there are issues
with trying to use this as a Mailman HTML_TO_PLAIN_TEXT_COMMAND because
it gets the input charset from the message's Content-Type: header and
none of the message's headers are passed to HTML_TO_PLAIN_TEXT_COMMAND.
Also, it specifies the output charset as utf-8, but Mailman will not
change the charset parameter in the converted MIME part. It only changes
the MIME type from text/html to text/plain so if the original HTML
charset is not utf-8, creating utf-8 output would be wrong.
While one could use some w3m command in HTML_TO_PLAIN_TEXT_COMMAND, the
appropriate command might be something like
w3m -dump -o display_link_number=1 -cols 78 -T text/html %(filename)s
without the -I and -O options, and this could wind up with the same
charset issues as lynx.
