Thanks, but that's a bit of a sledge hammer!  It looses all the other
settings, and duplicates where I specify the viewer.

I'd like mailcap.el to get the setting from ~/.mailcap.  My current
work-around is to

  (require 'mailcap)
  (setq mailcap-mime-data nil)
  (mailcap-parse-mailcaps nil t)

in .emacs, but that's also rather crude because it loses the default
settings from mailcap-user-mime-data, some of which may be useful (I
have not looked at them all).  Not to mention doing all the work twice.
