Making mutt *not* use mozilla to view html body/attachments

I don't know why it is non-obvious, but I finally tracked down to how have mutt use a text web browser (lynx|links) to display email with HTML bodies or attachments.

In your ~/.mailcap, put this:

text/html; lynx %s; nametemplate=%s.html

A cryptic reply here pointed to the right part in the Mutt manual
